Quantum computing has long been dominated by proprietary machines locked behind corporate and national lab firewalls, but a different model is starting to take shape. A growing coalition of ...

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.

A research group at the University of Geneva (UNIGE) demonstrates that the state of a quantum system can be inferred through indirect measurements when the system interacts with its surrounding ...

Quantum chaos – the study of quantum systems whose classical analogues exhibit chaotic behaviour – has rapidly evolved into a vibrant field that integrates nonlinear dynamics, fractal geometry and ...

Nvidia claims to have kicked off the “quantum-GPU computing era,” unveiling a way for quantum computers to interconnect with classical systems. Revealed at the chip giant’s GTC event in Washington, ...

Scientists from the National University of Singapore (NUS) have discovered that atomic-scale substitutional dopants in ultra-thin two-dimensional (2D) materials can act as stable quantum systems ...

Quantum computing promises extraordinary power, but that same power may expose new security weaknesses. Quantum computers are expected to deliver dramatic gains in processing speed and capability, ...

Quantum walks are changing the way scientists think about computation. They use the strange and powerful rules of quantum physics—such as superposition, interference, and entanglement—to solve ...

Quantum systems tend to become less “quantum-y” as they interact with their environment. So when developing a mathematical description, it’s usually simpler just to view them as being closed off from ...
