It is for the first time that quantum simulation for high-energy physics (HEP) is studied in the
US decadal particle-physics community planning, and in fact until recently, this was not …

Advances in isolating, controlling and entangling quantum systems are transforming what
was once a curious feature of quantum mechanics into a vehicle for disruptive scientific and …

The variational quantum eigensolver (VQE) is an algorithm to compute ground and excited
state energy of quantum many-body systems. A key component of the algorithm and an …

We construct a primitive gate set for the digital quantum simulation of the binary tetrahedral
(BT) group on two quantum architectures. This non-Abelian discrete group serves as a crude …

We simulate, using nonperturbative methods, the real-time dynamics of small bubbles of
“false vacuum” in a quantum spin chain near criticality, where the low-energy physics is …

We explore the possibility to perform symmetry restoration with the variation after projection
technique on a quantum computer followed by additional postprocessing. The final goal is to …

Quantum computing technologies are making steady progress. This has opened new
opportunities for tackling problems whose complexity prevents their description on classical …

We describe the simulation of dihedral gauge theories on digital quantum computers. The
non-Abelian discrete gauge group DN—the dihedral group—serves as an approximation to …

With advances in quantum computing, new opportunities arise to tackle challenging
calculations in quantum field theory. We show that trotterized time-evolution operators can …

With a focus on universal quantum computing for quantum simulation, and through the
example of lattice gauge theories, we introduce rather general quantum algorithms that can …
