Quantum simulation of Hamiltonian dynamics seeks to replicate the time evolution of complex quantum systems on controllable quantum devices. Central to this endeavour is the representation of the ...

Researchers at Freie Universität Berlin, University of Maryland and NIST, Google AI, and Abu Dhabi set out to robustly estimate the free Hamiltonian parameters of bosonic excitations in a ...

One of the most frequently asked questions about quantum computers is a simple one: When will they be useful? If you talk to people in the field, you’ll generally get a response in the form of another ...

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 ...

Hermitian Hamiltonians are a fundamental concept in quantum mechanics, serving as the mathematical foundation for describing the energy and time evolution of quantum systems. They are named after the ...

Though "coupled oscillations" may not sound familiar, they are everywhere in nature. The term "coupled harmonic oscillators" describes interacting systems of masses and springs, but their utility in ...

Researchers from quantum computing companies Quanscient Oy and Haiqu Inc. today announced that they have developed a new quantum computing algorithm designed to make computational fluid dynamics ...

Physicists have done a remarkable job explaining the chaos of the universe with well-behaved equations, but certain situations remain mysterious. Among these are collections of many tiny particles — ...

IBM is unveiling IBM Quantum Nighthawk, its most advanced quantum processor yet and designed with an architecture to complement high-performing quantum software to deliver quantum advantage next year: ...
