Nonadiabatic Holonomic Quantum Computation via Path Optimization
Lingtong Ji, Yan Liang, P. Shen +1 more·May 19, 2022
Nonadiabatic holonomic quantum computation (NHQC) is implemented by fast evolution processes in a geometric way to withstand local noises. However, recent works of implementing NHQC are sensitive to the systematic noise and error. Here, we present a ...
Low-rank tensor decompositions of quantum circuits
Patrick Gelß, Stefan Klus, Sebastian Knebel +2 more·May 19, 2022
Quantum computing is arguably one of the most revolutionary and disrup-tive technologies of this century. Due to the ever-increasing number of potential applications as well as the continuing rise in complexity, the development, simulation, optimizat...
mat2qubit: A lightweight pythonic package for qubit encodings of vibrational, bosonic, graph coloring, routing, scheduling, and general matrix problems
Nicolas P. D. Sawaya·May 19, 2022
Preparing problems for execution on quantum computers can require many compilation steps. Automated compilation software is useful not only for easier and faster problem execution, but also for facilitating the comparison between different algorithmi...
Vacuum provides quantum advantage to otherwise simulatable architectures
C. Calcluth, A. Ferraro, G. Ferrini·May 19, 2022
We consider a computational model composed of ideal Gottesman-Kitaev-Preskill stabilizer states, Gaussian operations - including all rational symplectic operations and all real displacements -, and homodyne measurement. We prove that such architectur...
Complementarity between success probability and coherence in Grover search algorithm
Minghua Pan, Haozhen Situ, Shenggen Zheng·May 19, 2022
Coherence plays a very important role in Grover search algorithm (GSA). In this paper, we define the normalization coherence , where C is a coherence measurement. By virtue of the constraint of large N and Shannon's maximum entropy principle, a surpr...
Estimating the randomness of quantum circuit ensembles up to 50 qubits
Minzhao Liu, Junyu Liu, Y. Alexeev +1 more·May 19, 2022
Random quantum circuits have been utilized in the contexts of quantum supremacy demonstrations, variational quantum algorithms for chemistry and machine learning, and blackhole information. The ability of random circuits to approximate any random uni...
Applications of universal parity quantum computation
M. Fellner, A. Messinger, K. Ender +1 more·May 19, 2022
We demonstrate the applicability of a universal gate set in the parity encoding, which is a dual to the standard gate model, by exploring several quantum gate algorithms such as the quantum Fourier transform and quantum addition. Embedding these algo...
Machine learning applications for noisy intermediate-scale quantum computers
Brian Coyle·May 19, 2022
Quantum machine learning has proven to be a fruitful area in which to search for potential applications of quantum computers. This is particularly true for those available in the near term, so called noisy intermediate-scale quantum (NISQ) devices. I...
Universal Parity Quantum Computing.
M. Fellner, A. Messinger, K. Ender +1 more·May 19, 2022
We propose a universal gate set for quantum computing with all-to-all connectivity and intrinsic robustness to bit-flip errors based on parity encoding. We show that logical controlled phase gate and R_{z} rotations can be implemented in parity encod...
Exponential challenges in unbiasing quantum Monte Carlo algorithms with quantum computers
G. Mazzola, Giuseppe Carleo·May 18, 2022
Recently, Huggins et. al. [Nature, 603, 416-420 (2022)] devised a general projective Quantum Monte Carlo method suitable for implementation on quantum computers. This hybrid approach, however, relies on a subroutine -the computation of the local ener...

Unpil Baek, D. Hait, J. Shee +5 more·May 18, 2022
A balanced description of both static and dynamic correlations in electronic systems with nearly degenerate low-lying states presents a challenge for multi-configurational methods on classical computers. We present here a quantum algorithm utilizing ...

C. Carlet, Ulises Pastor-D'iaz, José M. Tornero·May 18, 2022
In this paper, we focus on the links between Boolean function theory and quantum computing. In particular, we study the notion of what we call fully-balanced functions and analyse the Fourier--Hadamard and Walsh supports of those functions having suc...

Hitarth Choubisa, Jehad Abed, Douglas Mendoza +5 more·May 18, 2022
To enable the accelerated discovery of materials with desirable properties, it is critical to develop accurate and efficient search algorithms. Quantum annealers and similar quantum-inspired optimizers have the potential to provide accelerated comput...

Sarmed A Rahman, R. Lewis, E. Mendicelli +1 more·May 18, 2022
Quantum computers offer the possibility to implement lattice gauge theory in Minkowski rather than Euclidean spacetime, thus allowing calculations of processes that evolve in real time. In this work, calculations within SU(2) pure gauge theory are abl...
