Online data is generally pretty secure. Assuming everyone is careful with passwords and other protections, you can think of it as being locked in a vault so strong that even all the world’s ...

In 2026, quantum computing reached a long-awaited commercial tipping point, moving decisively from the noisy intermediate-scale quantum (NISQ) era toward the first stages of fault-tolerant operation.

Quantum computing is coming faster than most realize.

To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these ...

Just this past month, both Google’s Quantum AI team and a Cal Tech startup named Oratomic both produced papers that stated ...

With around 26,000 qubits, the encryption could be broken in a day, the researchers report in a paper submitted March 30 to arXiv.org. Another prevalent form of encryption, RSA–2048, would require 100 ...

Researchers from Cleveland Clinic, RIKEN, and IBM have carried out the largest quantum-classical chemistry ...

With the rapid expansion of quantum computing hardware, efficiently compiling high-level quantum programs to run on physical quantum chips has become one of the central challenges in the field of ...
