Better-than-classical Grover search via quantum error detection and suppression
Bibek Pokharel, Daniel Lidar
Grover's search algorithm is one of the first quantum algorithms to exhibit a provable quantum advantage. It forms the backbone of numerous quantum applications and is widely used…
Scalable Measurement Error Mitigation via Iterative Bayesian Unfolding
Siddarth Srinivasan, Bibek Pokharel, Gregory Quiroz +1
Measurement error mitigation (MEM) techniques are postprocessing strategies to counteract systematic read-out errors on quantum computers (QC). Currently used MEM strategies face a…
Phase transitions in the frustrated Ising ladder with stoquastic and nonstoquastic catalysts
Kabuki Takada, Shigetoshi Sota, Seiji Yunoki +3
The role of nonstoquasticity in the field of quantum annealing and adiabatic quantum computing is an actively debated topic. We study a strongly-frustrated quasi-one-dimensional qu…
Chaos in the quantum Duffing oscillator in the semiclassical regime under parametrized dissipation
Andrew D. Maris, Bibek Pokharel, Sharan Ganjam Seshachallam +2
We study the quantum dissipative Duffing oscillator across a range of system sizes and environmental couplings under varying semiclassical approximations. Using spatial (based on K…
Investigating the Chinese Postman Problem on a Quantum Annealer
Ilaria Siloi, Virginia Carnevali, Bibek Pokharel +2
The recent availability of quantum annealers has fueled a new area of information technology where such devices are applied to address practically motivated and computationally dif…
Demonstration of fidelity improvement using dynamical decoupling with superconducting qubits
Bibek Pokharel, Namit Anand, Benjamin Fortman +1
Quantum computers must be able to function in the presence of decoherence. The simplest strategy for decoherence reduction is dynamical decoupling (DD), which requires no encoding…
