All realistic quantum systems interact with their environments and thereby must be considered as open quantum systems. When a quantum system is strongly coupled to its environment, the so-called ...

The Lieb-Schultz-Mattis (LSM) theorem is an important result in condensed matter physics. The LSM theorem states that a spin chain with half-integer spin and translation and rotation symmetry can not ...

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 ...

What if time is not as fixed as we thought? Imagine that instead of flowing in one direction – from past to future – time could flow forward or backwards due to processes taking place at the quantum ...

An analog-digital approach to quantum simulation could lay the foundations for the next generation of supercomputers to finally outpace their classical predecessors. Reading time 3 minutes Quantum ...

“The vision was to build a useful, large-scale quantum computer that could harness quantum mechanics — the ‘operating system’ of nature to the extent we know it today — to benefit society by advancing ...

Sitting in an office at QuEra Computing’s Boston headquarters, Yuval Boger was talking about the recent advancements made in quantum computing that are driving the chorus around an accelerated the ...

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, ...
