Quantum computing is being hailed as the future of data processing, with promises of performing calculations thousands of times faster than modern supercomputers while consuming magnitudes less electricity. And in the span of just two years the only commercially available quantum computer, the D-Wave One

You will not be surprised to learn that the NSA is spending nearly $80 million trying to build "a cryptologically useful quantum computer." The Washington Post just published details of the program, codenamed "Penetrating Hard Targets," based on documents supplied by Edward Snowden.

World record setting experiment brings quantum computing a step closer to reality
Posted in: Today's Chili
Despite recent successes in the field, creating a quantum computer is really hard. For one thing quantum bits in a super positioned state (or qubits, the basic unit of data for quantum computing) have a hard time surviving at room temperature. Typically, these superposition states last for only a few seconds, but in a recent experiment at Simon Fraser University in Burnaby , researchers were able to keep a quantum system alive for a full 39 minutes.
“These lifetimes are at least ten times longer than those measured in previous experiments,” explained Stephanie Simmons from the University of Oxford’s Department of Materials. “Having such robust, as well as long-lived, qubits could prove very helpful for anyone trying to build a quantum computer.” Even so, they aren’t particularly active ones – all of the qubits in the experiment shared the same quantum state. To perform actual calculations (and thus build a functioning quantum computer), a system would need to put multiple qubtis in different quantum states. Sound complicated? It sure is, but it’s a significant step forward to building the ultrafast computing platforms of tomorrow. Eager to learn more? Check out the official press release at the source link below.

What’s Wrong With Quantum Computing
Posted in: Today's Chili
You’ve heard plenty of people by now—including us—banging on about quantum computers, and how they’re the future of high-performance computing. Quantum computing, we’re meant to understand, is set to change the world. But despite its promise, it’s neither widely available nor particularly useful yet. Here’s why not.
