Blueprint for a Molecular-Spin Quantum Processor

A. Chiesa, S. Roca, S. Chicco, M.C. de Ory, A. Gómez-León, A. Gomez, D. Zueco, F. Luis, and S. Carretta

Phys. Rev. Applied 19, 064060 (2023) - Published 21 June, 2023

The physical implementation of any quantum computer still faces important issues related to scalability and error correction. This study sets up the blueprint for a quantum processor based on molecular spins coupled to superconducting resonators, which control different qudits, read out their final states, and establish coherent communication channels between them. The feasibility of this route is demonstrated by an accurate design of the resonator to reach the strong-coupling regime between a single photon and a single molecule. Very good results for proof-of-principle quantum algorithms and quantum simulations are obtained by numerical simulations of a realistic experimental scenario.

Magnon Bundle in a Strongly Dissipative Magnet

H.Y. Yuan, Jikun Xie, and Rembert A. Duine

Phys. Rev. Applied 19, 064070 (2023) - Published 26 June, 2023

The rise of quantum information science based on hybrid quantum systems bridges different areas of research and provides innovative perspectives on quantum technology. Magnons show great potential as information carriers, but generating robust quantum states of magnons in a scalable hybrid system remains an outstanding challenge. Here the authors consider a superconducting qubit coupled to magnets by the dipole interaction. With delicate frequency detuning between magnet and qubit, an exotic quantum state of magnons is found. Interestingly, magnetic dissipation helps to stabilize the quantum states, which readily involves a wide class of magnetic materials in quantum information.

Pure-State Photon-Pair Source with a Long Coherence Time for Large-Scale Quantum Information Processing

Bo Li, Yu-Huai Li, Yuan Cao, Juan Yin, and Cheng-Zhi Peng

Phys. Rev. Applied 19, 064083 (2023) - Published 29 June, 2023

This study presents an experimental technique to tackle technical obstacles in generating photon pairs in pure states with extended coherence times. Such photon sources are vital for large-scale quantum information processing. The authors successfully eliminate the frequency correlation of parametric photons using optimal filtering, which enables high-quality Hong-Ou-Mandel interference between two photon sources. This breakthrough has promising practical applications in quantum science and can facilitate engineering solutions for long-distance quantum interference.

Topological Transformation with Emerging Zero Modes in Multistable Metamaterials for Reprogrammable Flexural Stiffness

Lei Wu and Damiano Pasini

Phys. Rev. Applied 19, L061001 (2023) - Published 22 June, 2023

In situ tuning of elastic stiffness enriches the range of functionalities of mechanical metamaterials for next-generation multifunctional devices. While stiffness tunability has been demonstrated under compression and tension, tuning flexural stiffness in multistable materials is now addressed in this work. Researchers leverage a multistable topological transformation induced by internal contact to activate zero-energy modes that yield both stiff and soft flexural modes. This remarkable tunability of flexural stiffness endows the architecture with a reversible rigid-flexible switch, which could support diverse applications from soft robotics to medical devices.

Phys. Rev. Applied 19, L061002 (2023) - Published 23 June, 2023

Localized topological midgap states are important for their robustness against disorder, but their natural localization limits their application. In this Letter the authors use an acoustic system to experimentally verify the existence of bulk states that belong to the band and, despite being extended, are robust against Hermitian and non-Hermitian disorders. The robustness of these bulk states cannot be expressed using the usual bulk-boundary correspondence. These results lift the limitation on localized topological states and can be used to develop robust acoustic devices based on far-field waves, including far-field imaging.

Independent Operation of Two Waveguide-Integrated Quantum Emitters

C. Papon, Y. Wang, R. Uppu, S. Scholz, A.D. Wieck, A. Ludwig, P. Lodahl, and L. Midolo

Phys. Rev. Applied 19, L061003 (2023) - Published 27 June, 2023

Scaling up single-photon sources directly on a chip is a fundamental requirement for realizing quantum information protocols that demand scalable, integrated photonic qubits. Integrating multiple quantum emitters in a circuit has encountered major roadblocks in wavelength disparity and the lack of a compact excitation method. The authors demonstrate simultaneous excitation of two quantum dots in the same circuit and independent control of the emitters’ wavelengths, enabling two-photon quantum interference. Spectral diffusion is not as detrimental to the interference process as anticipated. These results address a longstanding challenge in quantum photonics.

In two-dimensional hole systems, the Rashba spin-orbit interaction leads to a spin-dependent momentum. A perpendicular magnetic field spatially separates holes with different spins, creating a mass spectrometer for spin. Spin-resolved magnetic focussing has been used to measure spin polarization from the amplitude of magnetic focussing peaks. In this work, The authors show that the k3 form of the Rashba spin-orbit interaction term for semiconductor holes changes the scattering rate, which has an exponential effect on the focussing peak amplitude. This result further demonstrates the impact of the Rashba spin-orbit interaction in the field of semiconductor hole spin physics.

The rise of quantum information science based on hybrid quantum systems bridges different areas of research and provides innovative perspectives on quantum technology. Magnons show great potential as information carriers, but generating robust quantum states of magnons in a scalable hybrid system remains an outstanding challenge. Here the authors consider a superconducting qubit coupled to magnets by the dipole interaction. With delicate frequency detuning between magnet and qubit, an exotic quantum state of magnons is found. Interestingly, magnetic dissipation helps to stabilize the quantum states, which readily involves a wide class of magnetic materials in quantum information.

This study presents an experimental technique to tackle technical obstacles in generating photon pairs in pure states with extended coherence times. Such photon sources are vital for large-scale quantum information processing. The authors successfully eliminate the frequency correlation of parametric photons using optimal filtering, which enables high-quality Hong-Ou-Mandel interference between two photon sources. This breakthrough has promising practical applications in quantum science and can facilitate engineering solutions for long-distance quantum interference.
