The prevailing assumption has been that Einstein’s theory of gravity must be modified, or ‘quantized’, in order to fit within quantum theory. This is the approach of two leading candidates for a quantum theory of […]
IBM Quantum System Two is the building block of quantum-centric supercomputing. IBM Quantum System Two is the bedrock for scalable quantum computation. It is now operational at IBMs lab in Yorktown Heights, NY. It is […]
Insider Brief PUZZLE X, a forum on Exponential Technologies, hosted the first-ever Quantum Assembly at Barcelona recently. Zina Cinker, PUZZLE X Chief Creator, led the “Quantum Key Stakeholder Assembly,” to provide a platform for discussing […]
It’s not often that 5-year-olds can grasp questions at the frontiers of computer science, but it can happen. Suppose, for instance, that a kindergartner named Alice has two apples, but she prefers oranges. Fortunately, her […]
An international research team led by quantum physicist Markus Arndt (University of Vienna) has achieved a breakthrough in the detection of protein ions: Due to their high energy sensitivity, superconducting nanowire detectors achieve almost 100% […]
A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein’s classical concept of spacetime has been announced in two papers published simultaneously by UCL (University College London) physicists. Click to rate this […]
The field of attosecond physics was established with the mission of exploring light–matter interactions at unprecedented time resolutions. Recent advancements in this field have allowed physicists to shed new light on the quantum dynamics of […]
Quantum 7, 1195 (2023). https://doi.org/10.22331/q-2023-12-04-1195 The recovery of fragile quantum states from decoherence is the basis of building a quantum memory, with applications ranging from quantum communications to quantum computing. Many recovery techniques, such as […]
Quantum 7, 1194 (2023). https://doi.org/10.22331/q-2023-12-04-1194 A standard approach to quantifying resources is to determine which operations on the resources are freely available, and to deduce the partial order over resources that is induced by the […]
Quantum 7, 1193 (2023). https://doi.org/10.22331/q-2023-12-04-1193 The quasicharge superconducting qubit realizes the dual of the transmon and shows strong robustness to flux and charge fluctuations thanks to a very large inductance closed on a Josephson junction. […]
