Implementing Clifford Gates on Stabilizer Codes via Measurement
D. Banfield, Heather Leitch, A. Kay·Oct 25, 2022
We describe a method to use measurements and correction operations in order to implement the Clifford group in a stabilizer code, generalising a result from [Bombin,2011] for topological subsystem colour codes. In subsystem stabilizer codes of distan...
Digital Quantum Simulation and Circuit Learning for the Generation of Coherent States
Ruilin Liu, Sebastián V. Romero, I. Oregi +3 more·Oct 25, 2022
Coherent states, known as displaced vacuum states, play an important role in quantum information processing, quantum machine learning, and quantum optics. In this article, two ways to digitally prepare coherent states in quantum circuits are introduc...
Resource-efficient simulation of noisy quantum circuits and application to network-enabled QRAM optimization
Lu'is Bugalho, E. Z. Cruzeiro, Kevin C. Chen +3 more·Oct 24, 2022
Giovannetti, Lloyd, and Maccone (2008) proposed a quantum random access memory (QRAM) architecture to retrieve arbitrary superpositions of N (quantum) memory cells via quantum switches and $$O(\log (N))$$ O ( log ( N ) ) address qubits. Toward physic...
Variational quantum eigensolver for causal loop Feynman diagrams and directed acyclic graphs
Giuseppe Clemente, Arianna Crippa, K. Jansen +5 more·Oct 24, 2022
We present a variational quantum eigensolver (VQE) algorithm for the efficient bootstrapping of the causal representation of multiloop Feynman diagrams in the Loop-Tree Duality (LTD) or, equivalently, the selection of acyclic configurations in direct...
Dual unitaries as maximizers of the distance to local product gates
Shrigyan Brahmachari, R. Rajmohan, S. A. Rather +1 more·Oct 24, 2022
TThe problem of finding the resource free, closest local unitary, to any bipartite unitary gate $U$ is addressed. Previously discussed as a measure of nonlocality, the distance $K_D(U)$ to the nearest product unitary has implications for circuit comp...
Approximate Quantum Random Access Memory Architectures
Koustubh Phalak, Junde Li, Swaroop Ghosh·Oct 24, 2022
Quantum supremacy in many applications using well-known quantum algorithms rely on availability of data in quantum format. Quantum Random Access Memory (QRAM), an equivalent of classical Random Access Memory (RAM), fulfills this requirement. However,...
Autonomous quantum error correction and fault-tolerant quantum computation with squeezed cat qubits
Qiang-Da Xu, G. Zheng, Yu-Xin Wang +3 more·Oct 24, 2022
We propose an autonomous quantum error correction scheme using squeezed cat (SC) code against excitation loss in continuous-variable systems. Through reservoir engineering, we show that a structured dissipation can stabilize a two-component SC while ...
Finding maximal quantum resources
Jonathan Steinberg, O. Gühne·Oct 24, 2022
For many applications the presence of a quantum advantage crucially depends on the availability of resourceful states. Although the resource typically depends on the particular task, in the context of multipartite systems entangled quantum states are...
Implementation of Trained Factorization Machine Recommendation System on Quantum Annealer
Chen-Yu Liu, Hsin-Yu Wang, Pei-Yen Liao +2 more·Oct 24, 2022
Factorization Machine (FM) is the most commonly used model to build a recommendation system since it can incorporate side information to improve performance. However, producing item suggestions for a given user with a trained FM is time-consuming. To...
Track reconstruction at the LUXE experiment using quantum algorithms
Arianna Crippa, L. Funcke, T. Hartung +8 more·Oct 24, 2022
LUXE (Laser Und XFEL Experiment) is a proposed experiment at DESY which will study Quantum Electrodynamics (QED) in the strong-field regime, where QED becomes non-perturbative. Measuring the rate of created electron-positron pairs using a silicon pix...

Jiheng Duan, Minghui Li, H. Ian·Oct 23, 2022
Modern cryptographic protocols rely on sophisticated hash functions to generate quasi-unique numbers that serve as signatures for user authentication and other security verifications. The security could be compromised by finding texts hash-mappable t...

Youssef Moawad, W. Vanderbauwhede, R. Steijl·Oct 23, 2022
For efficient hardware-accelerated simulations of quantum circuits, we can define hardware-specific quantum-circuit transformations. We use a functional programming approach to create a quantum-circuit analysis and transformation method implemented i...
