Quantum computers promise to revolutionize whole industries by outperforming classical computers on complex calculations. They just need to be colder than the coldest natural place in the universe.

Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based spin qubits make it a promising material for scalable quantum computing.

They went on to show this approach could allow a quantum computer to break 256-bit elliptic curve cryptography (ECC) in 10 days while using 100 times less overhead than previously estimated. In a second paper,

A team of physicists set out to test some of the most exciting claims in quantum computing—and found a very different story. Instead of confirming breakthroughs, their careful replication studies revealed that signals once hailed as major advances could actually be explained in simpler ways.

An American physicist and Canadian computer scientist received the A.M. Turing Award on Wednesday for their groundbreaking work on quantum key cryptography.

Quantum computing has crossed a line that classical machines cannot easily follow, pushing simulations of matter and forces into regimes that even the largest supercomputers struggle to touch. Instead of toy models or contrived benchmarks, researchers are ...

Caltech researchers cut quantum computing qubit estimates by 100x, putting encryption-breaking quantum computers theoretically within reach this decade.

Four different quantum systems with four different types of qubits were on display at Nvidia GTC, here's how they all work.

Australia’s quantum push is accelerating, with real systems, bold timelines, and breakthroughs like quantum twins signaling a shift in the global tech race.

Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, guided by geometry too small to see with the naked eye.
