Quantum Electronic Circuits for Multicritical Ising Models
Ananda Roy
Multicritical Ising models and their perturbations are paradigmatic models of statistical mechanics. In two space-time dimensions, these models provide a fertile testbed for invest…
Ising Meson Spectroscopy on a Noisy Digital Quantum Simulator
Christopher Lamb, Yicheng Tang, Robert Davis +1
Quantum simulation has the potential to be an indispensable technique for the investigation of non-perturbative phenomena in strongly-interacting quantum field theories (QFTs). In…
Soliton Confinement in a Quantum Circuit
Ananda Roy, Sergei L. Lukyanov
Confinement of topological excitations into particle-like states - typically associated with theories of elementary particles - are known to occur in condensed matter systems, aris…
Entanglement entropy in critical quantum spin chains with boundaries and defects
Ananda Roy, Hubert Saleur
Entanglement entropy (EE) in critical quantum spin chains described by 1+1D conformal field theories contains signatures of the universal characteristics of the field theory. Bound…
The quantum sine-Gordon model with quantum circuits
Ananda Roy, Dirk Schuricht, Johannes Hauschild +2
Analog quantum simulation has the potential to be an indispensable technique in the investigation of complex quantum systems. In this work, we numerically investigate a one-dimensi…
Quantum-limited Parametric Amplification with Josephson Circuits in the Regime of Pump Depletion
Ananda Roy, Michel Devoret
Linear parametric amplification is a key operation in information processing. Our interest here is quantum-limited parametric amplification, , amplification of quantum signal…
