Local minima in quantum systems

Summary by Nature
Finding ground states of quantum many-body systems is known to be hard for both classical and quantum computers. Consequently, when a quantum system is cooled in a low-temperature thermal bath, the ground state cannot always be found efficiently. Instead, the system may become trapped in a local minimum of the energy. In this work, we study the problem of finding local minima in quantum systems under thermal perturbations. Although local minima …

Even Quantum Computers Can Benefit from Self-Improvement

When Albert Einstein first described quantum entanglement in 1935, he used terms like “spooky” due to its odd behaviour. It's highly unlikely he ever envisioned these odd particles becoming the backbone of a quantum computer revolution. At that time, Quantum physics was unlike anything the world had seen before, and it remains a cutting-edge science that has the potential to reshape the world as you know it. Today, quantum computers continue to …
