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

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

In a world where processing power is often a bottleneck, breaking the quantum barrier is expected to lead to huge benefits for businesses and society at large. Here are some of the key facts and statistics around quantum computing. 1. Quantum computing aims to take advantage of unusual properties that matter exhibits once we begin to study it at a level of detail below atomic level – the sub-atomic, or quantum level. 2. While conventional computer use binary “bits” (one and z

A breakthrough in studying light might just be the ticket to the future of quantum computing. Researchers at École Polytechnique Fédérale de Lausanne (EPFL) have found a way to determine how light behaves beyond the limitations of wavelengths, opening the door to encoding quantum data in a sci-fi style holographic light pattern. The team took advantage of the quantum nature of the interaction between electrons and light to separate beams in terms energy, not space that let th
