Toward a multi-core ultra-fast optical quantum processor: 43-GHz bandwidth real-time amplitude measurement of 5-dB squeezed light using modularized optical parametric amplifier with 5G technology

A. Inoue et al.

Summary: In this work, a real-time amplitude measurement method for continuous-variable optical quantum information processing is developed using a modular optical parametric amplifier (OPA) and a broadband balanced photodiode. This method improves the clock frequency limitation of homodyne detectors and enables the realization of high clock frequency optical quantum computers and multi-core systems.

Parameterized Two-Qubit Gates for Enhanced Variational Quantum Eigensolver

Stig Elkjaer Rasmussen et al.

Summary: This study focuses on the effect of parameterized two-qubit gates in the variational quantum eigensolver. By simulating the algorithm using fixed and parameterized two-qubit gates, it is shown that the parameterized versions outperform the fixed versions in terms of best energy and reducing outliers.

Efficient generation of entangled multiphoton graph states from a single atom

Philip Thomas et al.

Summary: This article introduces a deterministic protocol for creating photonic entanglement with a single memory atom in a cavity. By interleaving controlled single-photon emissions with tailored atomic qubit rotations, it is possible to efficiently grow multi-photon GHZ states and linear cluster states.

The Variational Quantum Eigensolver: A review of methods and best practices

Jules Tilly et al.

Summary: The variational quantum eigensolver (VQE) is a method used to compute the ground state energy of a Hamiltonian, which is important in quantum chemistry and condensed matter physics. It has the advantage of being able to model complex wavefunctions in polynomial time, making it a promising application for quantum computing. However, there are still many open questions regarding optimization, quantum noise, and other challenges, which require further research and exploration.

Deterministic multi-mode gates on a scalable photonic quantum computing platform

Mikkel V. Larsen et al.

Summary: Researchers have proposed and demonstrated a method for implementing multi-mode measurement-induced quantum gates in a large two-dimensional optical cluster state through optical measurements. They have successfully executed a small quantum circuit on a three-mode input state and believe that fault-tolerant universal quantum computing is possible with this platform by improving cluster-state entanglement and supplying states with specific encoding.

Demonstration of a High-Fidelity CNOT Gate for Fixed-Frequency Transmons with Engineered ZZ Suppression

A. Kandala et al.

Summary: This study introduces a novel coupling architecture for transmon qubits that improves two-qubit gate performance and suppresses cross talk; by using two fixed frequency coupling elements, it achieves intrinsic suppression of static ZZ while maintaining large effective coupling rates; through cross-resonance interaction, a 180 ns single-pulse controlled NOT (CNOT) gate with a fidelity of 99.77% is demonstrated.

Measurement-Based Variational Quantum Eigensolver

R. R. Ferguson et al.

Summary: This approach utilizes measurement-based quantum computation principles, involving entangled resource states and local measurements, and presents two measurement-based VQE schemes, introducing a new method for constructing variational families and translating circuit-based schemes. Both schemes offer specific advantages in terms of required resources and coherence times.
