Uncovering and Circumventing Noise in Quantum Algorithms via Metastability
Antonio Sannia, Pratik Sathe, Luis Pedro GarcÃa-Pintos
The presence of noise is the primary challenge in realizing fault-tolerant quantum computers. In this work, we introduce and experimentally validate a novel strategy to circumvent…
Quantum Uncertainty Relations for Thermodynamic Energy Flows
Pratik Sathe, Luis Pedro GarcÃa-Pintos, Francesco Caravelli
The Heisenberg uncertainty relation, which links the uncertainties of the position and momentum of a particle, has an important footprint on the quantum behavior of a physical syst…
Classical Thermometry of Quantum Annealers
George Grattan, Pratik Sathe, Cristiano Nisoli
Quantum annealers are emerging as programmable, dynamical experimental platforms for probing strongly correlated spin systems. Yet key thermal assumptions, chiefly a Gibbs-distribu…
Probing Antiferromagnetic Hysteresis on Programmable Quantum Annealers
Elijah Pelofske, Pratik Sathe, Cristiano Nisoli +1
Using programmable analog quantum annealing processors, we implement a sampling-based magnetic hysteresis protocol to probe the counterintuitive notion of magnetic memory in antife…
Magnetic Memory and Hysteresis from Quantum Transitions: Theory and Experiments on Quantum Annealers
Frank Barrows, Elijah Pelofske, Pratik Sathe +2
Quantum annealing leverages quantum tunneling for non-local searches, thereby minimizing memory effects that typically arise from metastabilities. Nonetheless, recent work has demo…
Magnetic Hysteresis Experiments Performed on Quantum Annealers
Elijah Pelofske, Frank Barrows, Pratik Sathe +1
While quantum annealers have emerged as versatile and controllable platforms for experimenting on correlated spin systems, the important phenomenology of magnetic memory and hyster…
