Collective behavior is an unusual phenomenon in condensed-matter physics. When quantum spins interact together as a system, ...

Quantum mechanics continues to offer profound insights into the fundamental nature of matter and energy, and the use of special functions plays a critical role in obtaining exact analytical solutions ...

A new unified theory connects two fundamental domains of modern quantum physics: It joins two opposite views of how a single ...

Nonequilibrium Green's functions (NEGF) have emerged as a pivotal theoretical framework for investigating the time-dependent behaviour of quantum many-body systems. By tracking the evolution 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.

It has demonstrated the powerful ability of a quantum computer to perform certain computational tasks more efficiently than a classical computer. Thus, to show quantum advantages is a key problem in ...

IBM today launched the Qiskit Functions Catalog, a new set of services that aims to make programming quantum computers easier by abstracting away many of the complexities of working with these ...

Quantum computing is in its infancy, but its potential has sparked intense exploration. This article examines three major trajectories that will shape the future of quantum computing: the gate-based ...

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, ...

Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...
