What does the inside of a carbon atom’s nucleus look like? A new study by Forschungszentrum Jülich, Michigan State University and the University of Bonn provides the first comprehensive answer to this question. In the […]
During fleeting fits, the sun occasionally hurls a colossal amount of energy into space. Called solar flares, these eruptions last for mere minutes, and they can trigger catastrophic blackouts and dazzling auroras on Earth. But […]
Seeking new techniques to enable quantum networking, Harvard University researchers have developed a novel laser-based strategy for creating single-atom, near-surface material defects, which can be used to form qubits, the most fundamental units of quantum […]
Quantum 7, 1008 (2023). https://doi.org/10.22331/q-2023-05-15-1008 We describe a complete method for a precise study of gravitational interaction between two nearby quantum masses. Since the displacements of these masses are much smaller than the initial separation […]
Quantum 7, 1007 (2023). https://doi.org/10.22331/q-2023-05-15-1007 We propose, formulate and examine novel quantum systems and behavioral phases in which momentary choices of the system’s memories interact in order to source the internal interactions and unitary time […]
Quantum 7, 1006 (2023). https://doi.org/10.22331/q-2023-05-15-1006 Quantum computing testbeds exhibit high-fidelity quantum control over small collections of qubits, enabling performance of precise, repeatable operations followed by measurements. Currently, these noisy intermediate-scale devices can support a sufficient […]
Quantum 7, 1005 (2023). https://doi.org/10.22331/q-2023-05-15-1005 Bias-tailoring allows quantum error correction codes to exploit qubit noise asymmetry. Recently, it was shown that a modified form of the surface code, the XZZX code, exhibits considerably improved performance […]
Quantum 7, 1004 (2023). https://doi.org/10.22331/q-2023-05-15-1004 Quantum many-body scarring is a paradigm of weak ergodicity breaking arising due to the presence of special nonthermal many-body eigenstates that possess low entanglement entropy, are equally spaced in energy, […]
Insider Brief ISARA named Atsushi Yamada chief executive officer and Amit Mital was named executive chairman. The executives bring significant cryptographic and technological leadership experience in enterprise and government. Critical Quote: “ISARA has an excellent […]
Quantum 7, 1003 (2023). https://doi.org/10.22331/q-2023-05-15-1003 The advantage that quantum systems provide for certain quantum information processing tasks over their classical counterparts can be quantified within the general framework of resource theories. Certain distance functions between […]
