It’s fascinating to think about the power in our pocket today’s smartphones have the computing power of a military computer from 50 years ago that was the size of an entire room. However, even with the phenomenal strides we made in technology and classical computers since the onset of the computer revolution, there remain problems that classical computers just can’t solve. Many believe quantum computers are the answer. Now that we have made the switching and memory units of c

For the first time, researchers have measured the accuracy of two-qubit logic operations in silicon, an advance that may help develop full-scale quantum processor. All quantum computations can be made up of one-qubit operations and two-qubit operations, which are the central building blocks of quantum computing. In 2015, researchers at the University of New South Wales (UNSW) in Australia were the first to build a quantum logic gate in silicon, making calculations between two

MIT researchers have designed a way to generate, at room temperature, more single photons for carrying quantum information. The design, they say, holds promise for the development of practical quantum computers. Quantum emitters generate photons that can be detected one at a time. Consumer quantum computers and devices could potentially leverage certain properties of those photons as quantum bits ("qubits") to execute computations. While classical computers process and store

Honeywell International Inc. threw down the gauntlet to Google and IBM in the race to create a new kind of supercomputer, announcing its own breakthrough in the arcane world of quantum mechanics. “We have a very unique technology that we believe is as good or better than anything that’s out there today,” CEO Darius Adamczyk announced on May 14. The company pegs the potential market for quantum-computing technology at $50 billion. Ten years of quiet work lies behind the bold s

Quantum cryptography holds both promises and threats for our current cryptographic infrastructure. The most obvious threat is quantum computers could decrypt data that’s been encrypted using many of our current systems. But it also holds the promise of secure communications channels for key distribution. Eventually, using quantum technology, it may even be possible to build entire encryption systems that are considered unbreakable. Almost all widely used encryption systems re

People who attend the Web Summit in Lisbon are familiar with how clogged the Portuguese city's streets get after thousands exit the event, where only one main traffic artery is available to ferry away visitors. This year, however, attendees will be able to download an app from Volkswagen Group and Canadian tech company D-Wave to predict the best route to any given destination. Real-time data is employed to mitigate the chaos, but the real purpose is to broaden awareness of th
