Riemannian quantum circuit optimization for Hamiltonian simulation
Ayse Kotil, R. Banerjee, Qunsheng Huang +1 more·Dec 15, 2022
Hamiltonian simulation, i.e. simulating the real time evolution of a target quantum system, is a natural application of quantum computing. Trotter-Suzuki splitting methods can generate corresponding quantum circuits; however, a faithful approximation...
A Graphical #SAT Algorithm for Formulae with Small Clause Density
Tuomas Laakkonen, K. Meichanetzidis, J. Wetering·Dec 15, 2022
We study the counting version of the Boolean satisfiability problem #SAT using the ZH-calculus, a graphical language originally introduced to reason about quantum circuits. Using this, we generalize #SAT to a weighted variant we call #SAT+-, which is...
Classical simulators as quantum error mitigators via circuit cutting
Ji Liu, Alvin Gonzales, Zain Saleem·Dec 14, 2022
We introduce an error mitigation framework that mitigates errors in a quantum circuit using circuit cutting. Our framework can be implemented in polynomial time for a wide variety of quantum circuits. Our technique involves cutting the circuit in suc...
A Novel State Connection Strategy for Quantum Computing to Represent and Compress Digital Images
Md. Ershadul Haque, M. Paul, Tanmoy Debnath·Dec 14, 2022
Quantum image processing draws a lot of attention due to faster data computation and storage compared to classical data processing systems. Converting classical image data into the quantum domain and state label preparation complexity is still a chal...
Time-dependent Rabi frequencies to protect quantum operations on an atomic qutrit by continuous dynamical decoupling
Adonai Hilário da Silva, R. Napolitano, F. Fanchini +1 more·Dec 14, 2022
We investigate the form required for the time-dependent Rabi frequencies involved in a procedure capable to protect the action of quantum gates on an atomic qutrit by means of external fields continuously decoupling the system from the environmental ...
NFNet: Non-interacting Fermion Network for Efficient Simulation of Large-scale Quantum Systems
Pengyuan Zhai, S. Yelin·Dec 12, 2022
We present NFNet, a PyTorch-based framework for polynomial-time simulation of large-scale, continuously controlled quantum systems, supporting parallel matrix computation and auto-differentiation of network parameters. It is based on the non-interact...
Architectures for Multinode Superconducting Quantum Computers
James Ang, G. Carini, Yanzhu Chen +30 more·Dec 12, 2022
Many proposals to scale quantum technology rely on modular or distributed designs where individual quantum processors, called nodes, are linked together to form one large multinode quantum computer (MNQC). One scalable method to construct an MNQC is ...
A SAT Approach to the Initial Mapping Problem in SWAP Gate Insertion for Commuting Gates
A. Matsuo, S. Yamashita, D. Egger·Dec 12, 2022
Most quantum circuits require SWAP gate insertion to run on quantum hardware with limited qubit connectivity. A promising SWAP gate insertion method for blocks of commuting two-qubit gates is a predetermined swap strategy which applies layers of SWAP...

We present an experimental implementation of a two-qubit photonic quantum processor fabricated using femtosecond laser writing technology. We employ femtosecond laser writing to create a low-loss reconfigurable photonic chip, implementing precise sin...
Parasitic-Free Gate: An Error-Protected Cross-Resonance Switch in Weakly Tunable Architectures
Xuexin Xu, M. Ansari·Dec 11, 2022
In two-qubit gates activated by microwave pulses, by turning pulse on or off, the state of qubits are swapped between entangled or idle modes. In either mode, the presence of stray couplings makes qubits accumulate coherent phase error. However, the ...
Universal Qudit Gate Synthesis for Transmons
Laurin E. Fischer, A. Chiesa, F. Tacchino +3 more·Dec 8, 2022
Gate-based quantum computers typically encode and process information in two-dimensional units called qubits. Using $d$-dimensional qudits instead may offer intrinsic advantages, including more efficient circuit synthesis, problem-tailored encodings ...
Controlling photon polarisation with a single quantum dot spin
E. Mehdi, Manuel Gundin-Martinez, C. Millet +9 more·Dec 7, 2022
In the framework of optical quantum computing and communications, a major objective consists in building receiving nodes that implement conditional operations on incoming photons, using the interaction with a single stationary qubit. In particular, t...

Ewout van den Berg, S. Bravyi, J. Gambetta +3 more·Dec 7, 2022
Generating samples from the output distribution of a quantum circuit is a ubiquitous task used as a building block of many quantum algorithms. Here we show how to accomplish this task on a noisy quantum processor lacking full-blown error correction f...

Shihao Zhang, Kai Huang, Lvzhou Li·Dec 2, 2022
Current noisy intermediate-scale quantum (NISQ) devices can only execute small circuits with shallow depth, as they are still constrained by the presence of noise: quantum gates have error rates and quantum states are fragile due to decoherence. Henc...
