Proof of the Error Scaling for Universally Robust Dynamical Decoupling Sequences

Domenico D'Alessandro, Phattharaporn Singkanipa, Daniel Lidar

Universally robust dynamical decoupling (UR) sequences were proposed to compensate pulse imperfections arising from arbitrary experimental parameters while achieving high-order…

Demonstration of Exponential Quantum Speedup with Constant-Depth Compiled Circuits for Simon's Problem

Phattharaporn Singkanipa, Victor Kasatkin, Daniel A. Lidar

We demonstrate exponential algorithmic quantum speedup for a restricted-Hamming-weight version of Simon's problem, in which the hidden string is promised to satisfy $\text{HW}(…

Families of 2D subsystem stabilizer codes for universal Hamiltonian quantum computation with two-body interactions

Phattharaporn Singkanipa, Zihan Xia, Daniel A. Lidar

In the absence of fault tolerant quantum error correction for analog, Hamiltonian quantum computation, error suppression via energy penalties is an effective alternative. We constr…

Beyond unital noise in variational quantum algorithms: noise-induced barren plateaus and limit sets

P. Singkanipa, D. A. Lidar

Variational quantum algorithms (VQAs) hold much promise but face the challenge of exponentially small gradients. Unmitigated, this barren plateau (BP) phenomenon leads to an expone…

QISS: Quantum Industrial Shift Scheduling Algorithm

Anna M. Krol, Marvin Erdmann, Rajesh Mishra +5

In this paper, we show the design and implementation of a quantum algorithm for industrial shift scheduling (QISS), which uses Grover's adaptive search to tackle a common and impor…

Demonstration of Algorithmic Quantum Speedup for an Abelian Hidden Subgroup Problem

P. Singkanipa, V. Kasatkin, Z. Zhou +2

Simon's problem is to find a hidden period (a bitstring) encoded into an unknown 2-to-1 function. It is one of the earliest problems for which an exponential quantum speedup was pr…

Quantum Conference Key Agreement with Photon Loss

Phattharaporn Singkanipa, Pieter Kok

Conference key agreement (CKA) is an information processing task where more than two parties want to share a common secret key. Here, we present a loss-resilient protocol for CKA,…
