Quantum Simulation of Lindbladian Dynamics via Repeated Interactions
Matthew Pocrnic, Dvira Segal, Nathan Wiebe
The Lindblad equation generalizes the Schrödinger equation to quantum systems that undergo dissipative dynamics. The quantum simulation of Lindbladian dynamics is therefore non-uni…
Bypassing thermalization timescales in temperature estimation using prethermal probes
Nicholas Anto-Sztrikacs, Harry J. D. Miller, Ahsan Nazir +1
We introduce prethermal temperature probes for sensitive, fast and robust temperature estimation. While equilibrium thermal probes with a manifold of quasidegenerate excited states…
Multi-spin probes for thermometry in the strong-coupling regime
Marlon Brenes, Dvira Segal
We study the sensitivity of thermometric probes that are composed of spins coupled to a sample prepared at temperature . Our analysis extends beyond the weak-coupling limit…
Composite QDrift-Product Formulas for Quantum and Classical Simulations in Real and Imaginary Time
Matthew Pocrnic, Matthew Hagan, Juan Carrasquilla +2
Recent work has shown that it can be advantageous to implement a composite channel that partitions the Hamiltonian for a given simulation problem into subsets and such…
Variational Quantum Eigensolvers in the Era of Distributed Quantum Computers
Ilia Khait, Edwin Tham, Dvira Segal +1
The computational power of a quantum computer is limited by the number of qubits available for information processing. Increasing this number within a single device is difficult; i…
Hyper-acceleration of quantum thermalization dynamics by bypassing long-lived coherences: An analytical treatment
Felix Ivander, Nicholas Anto-Sztrikacs, Dvira Segal
We develop a perturbative technique for solving Markovian quantum dissipative dynamics, with the perturbation parameter being a small gap in the eigenspectrum. As an example, we ap…
