Apple’s over-the-ear headphones could feature noise-canceling


 The plot thickens. Last week, KGI analyst Ming-Chi Kuo reported that Apple has been working on over-the-ear headphones in addition to new AirPods. Today, Bloomberg confirms this information and adds that these new headphones could also feature noise-canceling capabilities. KGI said that this new product should be available at some point in Q4 2018, just in time for the holiday season. But… Read More

Google Drive provides 15GB of storage space for free, making it a good option for backing up and syncing files. Accessing your Google Drive account on Windows and macOS is easy, but using Google Drive on Ubuntu is different. It’s not hard to access your Google Drive files in Ubuntu Linux, you just have to know how to do it. Here’s how to do this using Gnome Online Accounts. Install Gnome Online Accounts The System Settings in Ubuntu includes an Online Accounts section, but that’s not the one we’re going to use. We’re going to install Gnome Online Accounts into...

Google’s new Bristlecone processor brings it one step closer to quantum supremacy


 Every major tech company is looking at quantum computers as the next big breakthrough in computing. Teams at Google, Microsoft, Intel, IBM and various startups and academic labs are racing to become the first to achieve quantum supremacy — that is, the point where a quantum computer can run certain algorithms faster than a classical computer ever could. Today, Google said that it… Read More

The New Skype Works Better on Old Androids


Microsoft has released an optimized version of Skype for anyone running older Android phones. Specifically, handsets running on Android 4.0.3 to 5.1. However, this optimized version of Skype is completely separate from Skype Lite. Which isn’t confusing at all. The Rise of Lightweight Apps With more parts of the developing world coming online, tech companies are bending over backwards to appeal to this influx of new users. However, people in developing countries are likely to own low-end Android phones incapable of running the latest apps. My mom gave me her old iPhone and I DON'T KNOW HOW ANYTHING WORKS. I've...

Your Phone Needs a Seat Too! Get a Car Phone Holder


car-smartphone-holder

Don’t use your phone while driving. It’s dangerous. A car phone holder allows you to safely follow GPS, listen to music, and even monitor performance. If you’ve never tried Android Auto or Apple CarPlay, you’re in for a treat. A car phone holder lets you keep the phone at eye level while driving. Let’s discuss the available types of car mounts and recommend some for each. Windshield/Dash Mount The classic form of car mount has a suction cup that you can cling to your windshield or dash of your car. They’re typically adjustable, so you can swing them in a...

A Preview of Bristlecone, Google’s New Quantum Processor




The goal of the Google Quantum AI lab is to build a quantum computer that can be used to solve real-world problems. Our strategy is to explore near-term applications using systems that are forward compatible to a large-scale universal error-corrected quantum computer. In order for a quantum processor to be able to run algorithms beyond the scope of classical simulations, it requires not only a large number of qubits. Crucially, the processor must also have low error rates on readout and logical operations, such as single and two-qubit gates.

Today we presented Bristlecone, our new quantum processor, at the annual American Physical Society meeting in Los Angeles. The purpose of this gate-based superconducting system is to provide a testbed for research into system error rates and scalability of our qubit technology, as well as applications in quantum simulation, optimization, and machine learning.
Bristlecone is Google’s newest quantum processor (left). On the right is a cartoon of the device: each “X” represents a qubit, with nearest neighbor connectivity.
The guiding design principle for this device is to preserve the underlying physics of our previous 9-qubit linear array technology1, 2, which demonstrated low error rates for readout (1%), single-qubit gates (0.1%) and most importantly two-qubit gates (0.6%) as our best result. This device uses the same scheme for coupling, control, and readout, but is scaled to a square array of 72 qubits. We chose a device of this size to be able to demonstrate quantum supremacy in the future, investigate first and second order error-correction using the surface code, and to facilitate quantum algorithm development on actual hardware.
2D conceptual chart showing the relationship between error rate and number of qubits. The intended research direction of the Quantum AI Lab is shown in red, where we hope to access near-term applications on the road to building an error corrected quantum computer.
Before investigating specific applications, it is important to quantify a quantum processor’s capabilities. Our theory team has developed a benchmarking tool for exactly this task. We can assign a single system error by applying random quantum circuits to the device and checking the sampled output distribution against a classical simulation. If a quantum processor can be operated with low enough error, it would be able to outperform a classical supercomputer on a well-defined computer science problem, an achievement known as quantum supremacy. These random circuits must be large in both number of qubits as well as computational length (depth). Although no one has achieved this goal yet, we calculate quantum supremacy can be comfortably demonstrated with 49 qubits, a circuit depth exceeding 40, and a two-qubit error below 0.5%. We believe the experimental demonstration of a quantum processor outperforming a supercomputer would be a watershed moment for our field, and remains one of our key objectives.

We are looking to achieve similar performance to the best error rates of the 9-qubit device, but now across across all 72 qubits of Bristlecone. We believe Bristlecone would then be a compelling proof-of-principle for building larger scale quantum computers. Operating a device such as Bristlecone at low system error requires harmony between a full stack of technology ranging from software and control electronics to the processor itself. Getting this right requires careful systems engineering over several iterations.

We are cautiously optimistic that quantum supremacy can be achieved with Bristlecone, and feel that learning to build and operate devices at this level of performance is an exciting challenge! We look forward to sharing the results and allowing collaborators to run experiments in the future.
