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 […]
