Light Waves Like Never Before: Scientists Unveil Groundbreaking Optical Quantum Detection

For the very first time, they are utilizing particular photon detectors– gadgets that can find private light particles– for so-called homodyne detection.The ability to define optical quantum states makes the approach an essential tool for quantum info processing.” Homodyne detection is an approach frequently used in quantum optics to investigate the wave-like nature of optical quantum states,” discusses Timon Schapeler from the Paderborn Mesoscopic Quantum Optics working group at the Department of Physics. Our outcomes could enable the advancement of extremely efficient homodyne detectors with single-photon delicate detectors,” says Schapeler.Working with continuous variables of light opens up interesting and new possibilities in quantum details processing beyond qubits, the normal computing systems of quantum computers.Reference: “Low-noise balanced homodyne detection with superconducting nanowire single-photon detectors” by Timon Schapeler, Tim J. Bartley, Maximilian Protte and Jan Sperling, 24 February 2024, Optica Quantum.DOI: doi:10.1364/ OPTICAQ.502201.
