Google Quantum Computer Solves Problem 1 Billion Times Faster Than Best Supercomputer Which Might Mean Quantum Supremacy

Published

on

Financial Times and CNET that a Google research paper was temporarily posted online this week which claim a Google quantum computer’s processor could perform a calculation in just over 3 minutes which would take 10,000 years on IBM’s Summit supercomputer. This would mean the quantum system is 1.5 to 2 billion times faster than a classical supercomputer for this problem. We do not know details of the problem and other researchers have to confirm the work.

This is only one problem or on class of problem and does not mean all problems. The IBM Summit has about 200 petaflops of performance. These kinds of claims need a lot of verification because other mathematicians and researchers could optimize the algorithm or performance of a regular computer to solve it faster than what the original researchers believed. The paper apparently was only available briefly.

Google Researchers are thus talking about Quantum Supremacy. This would be when quantum computers solve problems faster than classical or solve tasks beyond the capabilities of classical computers.

MIT Technology Review has a positive assessment, but there is a shortage of information and peer review confirmation.

In 2013, D-Wave Systems thought they could solve a problem 3600 times faster than regular computers. But other researchers determined that there were better algorithms and programs.

Google was involved in the 2013-2014 D-Wave claims of quantum speedup. Google would be more careful about claims. Google has a contract with NASA to verify quantum speedups vs classical. Getting absolutely sure about speedup involves a lot of testing and work

Nextbigfuture will have updates as the Google paper becomes public and there is verification. The paper was taken down until the peer review is completed.

A reader has passed along what is a quote from Intel, Jim Clarke, director of quantum hardware, Intel Labs:

Google’s recent update on the achievement of quantum supremacy is a notable mile marker as we continue to advance the potential of quantum computing. Achieving a commercially viable quantum computer will require advancements across a number of pillars of the technology stack.

We along with the industry are working to quickly advance all of those areas to realize the true potential of quantum computing. And while development is still at mile one of this the marathon, we strongly believe in the potential of this technology. “— Jim Clarke, director of quantum hardware, Intel Labs.

Partial abstract of the paper which NASA posted and then removed.

The tantalizing promise of quantum computers is that certain computational tasks might be executed exponentially faster on a quantum processor than on a classical processor. A fundamental challenge is to build a high-fidelity processor capable of running quantum algorithms in an exponentially large computational space. Here, we report using a processor with programmable superconducting qubits to create quantum states on 53 qubits, occupying a state space 2(exp53) ~ 10(exp16). Measurements fro…

Using a PlayStation 4 controller with your PC

Published

on

By

Microsoft’s Xbox controller has been the default gamepad for PC gamers for some time now, but you may prefer Sony’s competing — and also quite good — DualShock 4 controller. The good news is, you can easily configure it to work on Windows or macOS.

The PlayStation 4 gamepad’s ergonomic and efficient design cannot be denied. Whether you play first-person shooters, roleplaying games, or any other genre, the DS4 is crafted to feel comfortable in button placement, weight, and grip. Long-time PlayStation gamers may wish to use it on their PC games because of its familiarity. Others opt for it instead of spending money on a new controller. And, of course, the DualShock 4 controller is perfect for playing games with the Remote Play app on your computer.

Whatever the case may be, it is relatively simple to connect and use the DualShock 4 with your computer. There are a few quirks, though, which is why we thought a primer on setting up and using them would be prudent.

TL;DR

  • First: Unpair the PS4 controller from your console. Then connect it to your PC or Mac using the original cable (or buy a longer one) or use Bluetooth. More instructions on how to use Bluetooth can be read below.
  • On Windows: Download DS4Windows and use this to map the DualShock 4 controller and emulate an Xbox controller, so you gain native-like OS support. Steam Big Screen mode also has support for the PS4 controller.
  • On Mac: Using the most recent release of macOS Catalina 10.15 is highly encouraged as that will provide with the easiest integration. Steam for Mac and few other apps provide native controller support. More detail on that below.
  • PS4 Remote Play: Using the DualShock 4 with PlayStation’s Remote Play app is relatively painless since both PC and Mac have built-in support.

The DualShock 4 is more or less plug-and-play. It can be connected to both PCs and Macs via a compatible micro USB cable. The one that comes with the controller is fine but is a tad short and may not suit your computer set up. You can buy a 20-foot cable that should be more than enough for anyone’s needs.

However, who needs a cable when the controller is equipped with Bluetooth? Therefore this article will mostly focus on pairing it wirelessly.

Unpairing from PS4 and Pairing Mode

Whether you are planning to use your DualShock 4 with PC or Mac, you will first have to unpair it from the PlayStation, unless you bought it new, and it has never been paired. If that’s the case you may skip this step.

To unpair it, turn on your PS4 and go into the Settings menu. Scroll down and open the Devices sub-menu. Select Bluetooth Devices and then DualShock 4, and click on Disconnect. With your DS4 now unpaired, you are set to connect it with your Mac or PC via Bluetooth, but first, you need to get the controller into pairing mode.

To initiate pairing, simultaneously press and hold the PS and the Share buttons on the DS4 for about three seconds. You will know it is in pairing mode when the light on the front of the controller begins blinking white in a double flash pattern (above).

Connecting the controller to Mac and PC is a similar process, but setting it up with macOS is a bit more straightforward, so let’s start there.

Connecting the DS4 in macOS

With the controller in pairing mode, go to your Mac’s settings and open Bluetooth Preferences. It might take a few seconds or more while the Mac searches for the signal, so be patient. Eventually, a listing for it will appear.

We have seen various labels show up here — “wireless controller,” “DualShock 4 wireless controller,” even the raw MAC address has shown up before. Regardless of how it is listed, it will be obvious which device is the controller.

Next to the listing, click the Connect button. After a few seconds, the wireless controller will move to connected status. Also, the light on the front of the DS4 will be a steady light blue. Now you are good to go — well, almost. Skip to the Quirks and Game Support section to see what caveats we encountered.

Connecting the DS4 in Windows

With the controller in pairing mode, go into Windows Bluetooth settings. Click on “Add Bluetooth or other device.” A window will pop up with the top option to connect to a BT device. Click it, and on the next screen you should see an entry for “wireless controller.” Click that, and it will pair the controller.

Once the DS4 is connected, you would think that you are ready to go. After all, it will clearly show that the computer is connected and receiving a signal from the controller — it may have even run some driver installs. However, the DualShock will be useless when trying to run native games.

Since Windows does not have native support for the DS4, you will have to trick it into thinking you are using an Xbox 360 controller, which it does support. You can do this by downloading and installing an open-source program called DS4Windows. Features are listed on the official website, and you can download it from TechSpot Downloads. You won’t need this app if you plan to play only Steam games, which we will get to in a minute.

DS4Windows comes in a zipped file. Extract it and you will see two .exe files. DS4Udater.exe just downloads the latest drivers. For now, you should be good, but keep this in mind if you have problems down the road. The main program is DS4Windows.exe. Run this, and your DualShock will immediately have functionality in Windows. You can even use the DS4’s touchpad as a mini trackpad to move the cursor around. Pushing in on the pad emulates left-clicking.

With DS4Windows running in the background, you should not have any trouble playing games natively on your PC using the DualShock 4. However, you may wish to customize settings in-game to suit your button preferences.

Quirks and Game Support

Now for the “bad” news. Using a DualShock 4 on your computer can be a bit tricky at times. A lot of it depends on your system setup and what you are trying to do with the controller.

Windows users relying on DS4Windows should be good to go as long as the game you are playing has controller support. DS4Windows transforms the signals from the DS4 into Xbox 360 code, so it’s effectively remapped across the OS.

We also tested the DualShock 4 with Steam on PC, and it works great in “Big Screen” mode after a bit of tinkering. After starting the Steam launcher in Big Screen mode, you want to click on the Settings icon (the gear in the upper right). Click the Controller Settings tab and check the “PlayStation Configuration Support” box.

Using the DualShock 4 with PlayStation’s Remote Play app is relatively painless since the apps for both PC and Mac have built-in support. However, if you are running a version of macOS earlier than Catalina 10.15, you will need Sony’s DS4 Bluetooth dongle. This is unfortunate because the officially supported adapter goes for about $65 on Amazon, although you can find them for less on eBay.

Some Redditors have reported that you can use any Bluetooth adapter, and this may be true, but we have not tested to confirm this. We have tested the official dongle, and it solves Remote Play compatibility issues on older iterations of macOS.

With the Mac version of Steam, we encountered a few more problems and the solutions can vary a lot. The safest bet here is to run the latest macOS and Steam’s 64-bit launcher which are both new and are still catching up on receiving full support. For games that we could start, the DualShock worked fine. Big Screen mode gives you a very console-like experience with the benefit of PC-powered graphics, and any game you can launch in that mode will recognize the controller. Running Steam games outside of Big Screen mode, the DS4 didn’t work at all. It would seem that Big Screen works similarly to the PC’s DS4Windows app, translating controller input to the game.

All-in-all, the DualShock 4 is a great controller for your PC with just a few caveats. It would appear that Windows users have it easier than Mac gamers, but that is somewhat to be expected. With that said, Apple is making strides as of late and even native Xbox controller support recently was made available for its desktop OS.

Last week, Activision released the much-awaited Call of Duty Mobile on Android and iOS in partnership with the Chinese tech giant Tencent. The new battle royale game seems to be an instant hit as it has already crossed 100 million downloads, according to a report by app research firm SensorTower.

The report notes the game beat first-week download numbers achieved by other popular games such as PlayersUnknown BattleGround (PUBG) and Fortnite. While PUBG picked up 28 million downloads within the first week of launch, Fortnite had 22 million downloads.
It’s important to note PUBG was released in limited regions, and Fortnite was iOS-only at the beginning. On the flip side, Call of Duty Mobile launched on both platforms and in all countries except mainland China, Vietnam, and Belgium.All you need to know about the iPhone 11, the Pro, and Pro Max

PS4 Remote Play game streaming coming to non-Sony phones this week

Published

on

By

Devoted PlayStation users have for years called on Sony to bring official support for Remote Play game streaming app to non-Sony handsets, and it seems their demands will finally be met. Sony has announced to release the v7.00 update for the PlayStation 4 within this week, bringing the feature to a wider range of Android devices.

Remote Play has been around since the days of the PlayStation 3, but it could relay console games only to a handful of Xperia smartphones released after 2014. Back then, an XDA Forum member was able to port the feature to all rooted Android devices, but the implementation remained rough. The upcoming system update for the PS4 console aims to address this as it expands the scope of Remote Play to cover all Android devices — smartphones and tablets — running version 5.0 Lollipop or newer.

All you’ll need to do is download the PS4 Remote Play app from the Google Play Store after you’ve updated your gaming console with the latest firmware. The app is listed on the Play Store but it still isn’t compatible with non-Sony devices. This should probably change once Sony pushes the v7.00 update to its console. Notably, devices running Android 10 will be able to pair with Sony’s DualShock 4 wireless controllers over Bluetooth. Given how recent Android 10 is, not many are likely to take advantage of this feature.

In addition to this, Sony is also doubling the maximum Party size to 16 with this software update, besides bringing Chat Transcription to Party using the PS4 Second Screen app. Initially, this accessibility feature will only support US English and won’t be available outside the US. Some improvements to the audio quality and network connectivity have also been implemented.
