A team from UNIGE shows that it is possible to determine the state of a quantum system from indirect measurements when it is coupled to its environment.

Quantum physics is no longer confined to cryogenic chips and vacuum chambers. It is starting to seep into the machinery of ...

Quantum computers could rapidly solve complex problems that would take the most powerful classical supercomputers decades to ...

Researchers have developed a new protocol for characterizing quantum gate errors, paving the way toward more reliable quantum simulations and fault-tolerant quantum computing. Researchers have ...

Ripples spreading across a calm lake after raindrops fall—and the way ripples from different drops overlap and travel outward—is one image that helps us picture how a quantum computer handles ...

This diagram illustrates how the team reduces quantum circuit complexity in machine learning using three encoding methods—variational, genetic, and matrix product state algorithms. All methods ...

Can quantum physics enable better, cheaper, faster satellite photos? In a month or two, a startup will test a “quantum camera ...
