Simulating quantum mechanics is known to be a difficult computational problem, especially
when dealing with large systems. However, this difficulty may be overcome by using some …

Recent interest in aspects common to quantum information and condensed matter has
prompted a flurry of activity at the border of these disciplines that were far distant until a few …

In the field of quantum simulation, methods and tools are explored for simulating the
dynamics of a quantum system of interest with another system that is easier to control and …

Quantum simulators are controllable quantum systems that can be used to simulate other
quantum systems. Being able to tackle problems that are intractable on classical computers …

We review recent theoretical advances in cold atom physics concentrating on strongly
correlated cold atoms in optical lattices. We discuss recently developed quantum optical …

A random access memory (RAM) uses n bits to randomly address N= 2 n distinct memory
cells. A quantum random access memory (QRAM) uses n qubits to address any quantum …

We show that the physical system consisting of trapped ions interacting with lasers may
undergo a rich variety of quantum phase transitions. By changing the laser intensities and …

Exact first-principles calculations of molecular properties are currently intractable because
their computational cost grows exponentially with both the number of atoms and basis set …

A digital quantum simulator is an envisioned quantum device that can be programmed to
efficiently simulate any other local system. We demonstrate and investigate the digital …

Entanglement lies at the heart of quantum mechanics, and in recent years has been
identified as an essential resource for quantum information processing and computation …
