After 50 years of hunting, physicists have finally observed a new state of matter known as a quantum spin liquid. “It is a very special moment in the field,” says physicist Mikhail Lukin, co-director of the Harvard Quantum Initiative (HQI) and a senior author on the study in Science. “You can really touch, poke, and … Continue reading Quantum spin liquid observed in physics first
Finnish physicists have created an ultra-thin, 2D material with quantum properties that would usually only be made possible using rare earth minerals. But this new material was fabricated using only common materials. “Studying complex quantum materials is hindered by the properties of naturally occurring compounds,” says atomic physicist Peter Liljeroth from Aalto University. “Our goal … Continue reading Ultra-thin material mimics quantum entangled rare earth compounds
When we design an algorithm for encryption, we’re not devising some kind of secret code. In fact, the whole algorithm is open – it’s published, and well-known. The only part which is not known is this relatively short 128-bit piece of information – a simple, secret key. And every time you’d like to communicate, you … Continue reading Open algorithms and secret keys: will existing encryption solutions solace quantum?
Are you worried about someone listening into your calls, reading your emails, or watching your video chats? You’re not alone. The internet has changed the face of communication and how communication can be stolen, spied upon or manipulated, and it always gets harder to protect ourselves as technology evolves. This becomes even more difficult as … Continue reading Maths, encryption, and quantum computing
Is this the beginning of the end for online transactions? Physicists claim they've built a scalable quantum computer that could someday crack traditional security systems. Cathal O'Connell explains.
Quantum computing in silicon has moved a step closer to becoming a reality. Cathal O'Connell explains.
