Quantum computing breaktrhroughs including new hardware, smarter algorithms, and clearer signs of “quantum advantage,” bring ...

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 ...

New research suggests that a quantum computer could crack a crucial cryptography method with just 10,000 qubits.

Quantum computers struggle with a major flaw: their information vanishes unpredictably. Scientists have now created a new method that can measure this loss over 100 times faster than before. By ...

A newly developed encryption framework aims to protect video data from future quantum attacks, all while running on today's ...

Light moving through a tiny silicon structure does not look dramatic. It slips down narrow waveguides etched onto a chip, ...

“In quantum computers, information is transmitted and stored using so-called qubits (quantum bits). But quantum information ...

Quantum processors operate in environments engineered to eliminate nearly all external interference. That just might make ...

Quantum computers hit a crucial milestone for error-free calculation The new record holder is a quantum computer called Jiuzhang 4.0 that makes calculations using particles of light, or photons.

Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought ...

Researchers have revisited a long-known material and uncovered a way to dramatically enhance its performance by altering its structure at the nanoscale.

Future quantum computers will need to be less powerful than we thought to threaten the security of encrypted messages.
