Quantum simulation of open quantum systems seeks to replicate the dynamics of quantum devices interacting with surrounding environments. Such interactions give rise to non-unitary ...

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 ...

A research team at the Jülich Supercomputing Center, together with experts from NVIDIA, has set a new record in quantum simulation: for the first time, a universal quantum computer with 50 qubits has ...

Scientists at Google have revealed a new method of "quantum simulation" that uses computing power to mimic the behavior of a powerful quantum system. This approach, they argue, could lead to quantum c ...

When exposed to periodic driving, which is the time-dependent manipulation of a system's parameters, quantum systems can exhibit interesting new phases of matter that are not present in ...

Two weeks ago, D-Wave System announced a scientific breakthrough using their quantum annealing computers systems. They published in the esteemed journal @ScienceMagazine. Their newest annealing ...

Early community reaction has focused on both the potential and the practical challenges. Some researchers view the release as a step toward making quantum systems more programmable, noting that ...

Large-scale classical simulation of IQPE quantum circuits demonstrated in this work. Larger qubit counts and more Hamiltonian terms result in deeper circuits and longer simulation times. Osaka, Japan ...

Scientists in Germany have pulled off a staggering computing feat by fully simulating a 50-qubit quantum computer for the first time ever using Europe’s new exascale supercomputer, JUPITER. The ...

In the everyday world, governed by classical physics, the concept of equilibrium reigns. If you put a drop of ink into water, it will eventually evenly mix. If you put a glass of ice water on the ...

For six years, 48 qubits was the wall. No classical supercomputer on Earth could perform a universal, exact simulation of a ...
