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.

Researchers have developed a new method to significantly enhance quantum technology performance by using the cross-correlation of two noise sources to extend coherence time, improve control fidelity, ...

A new study uncovers how tiny misalignments in quantum communication links can quietly undermine security. Quantum key distribution (QKD) is a next generation method for protecting digital ...

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 ...

Scientists have used a new method to determine the characteristics of optical, i.e. light-based, quantum states. For the first time, they are using certain photon detectors -- devices that can detect ...

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

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

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 ...

You can cram much more quantum processing power into a given space if you use four different ways to store data on a single atom, according to new research. The method unlocks more powerful quantum ...
