Controlled-Controlled-Phase Gates for Superconducting Qubits Mediated by a Shared Tunable Coupler
N. J. Glaser, F. Roy, S. Filipp·Jun 24, 2022
Applications for noisy intermediate-scale quantum computing devices rely on the efficient entanglement of many qubits to reach a potential quantum advantage. Although entanglement is typically generated using two-qubit gates, direct control of strong...
Exploring ab initio machine synthesis of quantum circuits
Richard Meister, Cica Gustiani, S. Benjamin·Jun 22, 2022
Gate-level quantum circuits are often derived manually from higher level algorithms. While this suffices for small implementations and demonstrations, ultimately automatic circuit design will be required to realise complex algorithms using hardware-s...

Graph states are a family of stabilizer states which can be tailored towards various applications in photonic quantum computing and quantum communication. In this paper, we present a modular design based on quantum dot emitters coupled to a waveguide...
Single-step implementation of a hybrid controlled-not gate with one superconducting qubit simultaneously controlling multiple target cat-state qubits
Qi-Ping Su, Yu Zhang, Chuiping Yang·Jun 21, 2022
Hybrid quantum gates have recently drawn considerable attention. They play significant roles in connecting quantum information processors with qubits of different encoding and have important applications in the transmission of quantum states between ...
Dual unitary circuits in random geometries
Yusuf Kasim, T. Prosen·Jun 20, 2022
Recently introduced dual unitary brickwork circuits have been recognised as paradigmatic exactly solvable quantum chaotic many-body systems with tunable degree of ergodicity and mixing. Here we show that regularity of the circuit lattice is not cruci...
Quantum circuit optimization for multiple QPUs using local structure
Edwin Tham, Ilia Khait, Aharon Brodutch·Jun 20, 2022
Interconnecting clusters of qubits will be an essential element of scaling up future quantum computers. Operations between quantum processing units (QPUs) are usually significantly slower and costlier than those within a single QPU, so usage of the i...
Localization Detection Based on Quantum Dynamics
K. Kudo·Jun 18, 2022
Detecting many-body localization (MBL) typically requires the calculation of high-energy eigenstates using numerical approaches. This study investigates methods that assume the use of a quantum device to detect disorder-induced localization. Numerica...
