Researchers propose an unconventional way to generate light made from entangled photons. In the graphic above, photons meet the electrons of a helium atom, which then emits two entangled photons. Click to rate this post! […]
An ultracompact circularly polarized light source is a crucial component for the applications of classical and quantum optics information processing. The development of this field relies on the advances of two fields: quantum materials and […]
Quantum 6, 802 (2022). https://doi.org/10.22331/q-2022-09-08-802 The challenge of quantum computing is to combine error resilience with universal computation. Diagonal gates such as the transversal $T$ gate play an important role in implementing a universal set […]
NSA Releases Future Quantum-Resistant (QR) Algorithm Requirements for National Security Systems0 (0)
Insider Brief The National Security Agency (NSA) released the “Commercial National Security Algorithm Suite 2.0” (CNSA 2.0) Cybersecurity Advisory (CSA) to notify organizations of future quantum-resistant (QR) algorithms requirements for NSS — networks that contain classified […]
Quantum 6, 801 (2022). https://doi.org/10.22331/q-2022-09-08-801 We introduce unique class of cyclic quantum thermal machines (QTMs) which can maximize their performance at the finite value of cycle duration $tau$ where they are most irreversible. These QTMs […]
Insider Brief: Australian quantum computing hardware company Silicon Quantum Computing takes another significant step toward useful quantum computing. The company’s scientists have developed a new method that makes the critical readout stage of a quantum […]
When photons hurtle toward a black hole, most are sucked into its depths, never to return, or gently deflected away. A rare few, however, skirt the hole, making a series of abrupt U-turns. Some of […]
Quantum 6, 800 (2022). https://doi.org/10.22331/q-2022-09-08-800 We propose a continuous-variable (CV) SWAP test that requires no ancilla register, thereby generalizing the ancilla-free SWAP test for qubits. In this ancilla-free CV SWAP test, the computational basis measurement […]
Quantum 6, 799 (2022). https://doi.org/10.22331/q-2022-09-08-799 In certain regimes, the fidelity of quantum states will decay at a rate set by the classical Lyapunov exponent. This serves both as one of the most important examples of […]
Quantum 6, 798 (2022). https://doi.org/10.22331/q-2022-09-08-798 There is no unique way to encode a quantum algorithm into a quantum circuit. With limited qubit counts, connectivity, and coherence times, a quantum circuit optimization is essential to make […]
