A universal fault-tolerant quantum computer that can efficiently solve problems such as
integer factorization and unstructured database search requires millions of qubits with low …

The past few years have witnessed the concrete and fast spreading of quantum
technologies for practical computation and simulation. In particular, quantum computing …

Universal quantum computers are potentially an ideal setting for simulating many-body
quantum dynamics that is out of reach for classical digital computers. We use state-of-the-art …

Strongly coupled gauge theories far from equilibrium may exhibit unique features that could
illuminate the physics of the early universe and of hadron and ion colliders. Studying real …

Trotterization-based, iterative approaches to quantum simulation (QS) are restricted to
simulation times less than the coherence time of the quantum computer (QC), which limits …

To get the best possible results from current quantum devices error mitigation is essential. In
this work we present a simple but effective error mitigation technique based on the …

The nuclear shell model is one of the prime many-body methods to study the structure of
atomic nuclei, but it is hampered by an exponential scaling on the basis size as the number …

Computing quantum state fidelity will be important to verify and characterize states prepared
on a quantum computer. In this work, we propose novel lower and upper bounds for the …

Understanding how hydrodynamic behaviour emerges from the unitary evolution of the
many-particle Schrödinger equation is a central goal of non-equilibrium statistical …

The successes and limitations of statistical sampling for a sequence of models studied in the
context of lattice QCD are discussed and the need for new methods to deal with finite …
