Most people programming gate-level quantum computers now do so at the gate level, using standard gates such as X, Y, Z, CNOT, Hadamard, etc. However, quantum processors can also be programmed at the pulse level […]
Quark–gluon plasma is an extremely hot and dense state of matter in which the elementary constituents—quarks and gluons—are not confined inside composite particles called hadrons, as they are in the protons and neutrons that make […]
By Carolyn Mathas The already in-place multi-domain research association between Volkswagen Group (Wolfsburg, Germany) and Toronto-based Xanadu across material science, computational chemistry, battery technologies, and quantum algorithms, is taking on a new project—developing advanced quantum […]
Australian researchers have engineered a quantum box for polaritons in a two-dimensional material, achieving large polariton densities and a partially “coherent” quantum state. Click to rate this post! [Total: 0 Average: 0]You have already voted […]
First measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor0 (0)
Recent Australian-led research has provided a world’s first measurement of interactions between Fermi polarons in an atomically-thin 2D semiconductor, using ultrafast spectroscopy capable of probing complex quantum materials. Click to rate this post! [Total: 0 […]
Quantum 6, 844 (2022). https://doi.org/10.22331/q-2022-10-20-844 We propose and investigate a new method of quantum process tomography (QPT) which we call projected least squares (PLS). In short, PLS consists of first computing the least-squares estimator of […]
How does objective reality emerge from the palette of possibilities supplied by quantum mechanics? That question — the deepest and most vexed issue posed by the theory — is still the subject of arguments a […]
A research team at the Institute of Modern Physics (IMP) of the Chinese Academy of Sciences (CAS), together with their collaborators, have recently synthesized a new isotope, actinium-204, which is the lightest actinium isotope so […]
Quantum 6, 843 (2022). https://doi.org/10.22331/q-2022-10-20-843 According to the entropy accumulation theorem, proving the unconditional security of a device-independent quantum key distribution protocol reduces to deriving tradeoff functions, i.e., bounds on the single-round von Neumann entropy […]
Quantum 6, 842 (2022). https://doi.org/10.22331/q-2022-10-20-842 This paper proposes a new factorization algorithm for computing the phase factors of quantum signal processing. The proposed algorithm avoids root finding of high degree polynomials by using a key […]
