"Our knowledge of the nuclear forces is still far for complete"
Maria Goeppert Mayer - theoretical physicist, Nobel laureate in Physics.

If you speak spanish, Esperanza did a great video on questions about QC with Quantum Madrid.

"This risks creating an arms race": inside Europe's battle over the future of quantum computing

Since the 1960s, the rate of progress in every field of scientific inquiry – from drug discovery to climate forecasting, renewable energy to artificial intelligence – has depended, at least in part, on the ability of engineers to build smaller transistors.

Amazon's New Quantum Computer Design Relies On Tiny Schrödinger's Cats

A critical drawback of current quantum computers is how their inner workings are prone to errors. “If you look at the error rate gap in terms of where the hardware is now and where it needs to be to handle large-scale problems with known societal and commercial benefit, there's about a nine orders of magnitude gap,” says Oskar Painter, head of Amazon Web Services (AWS)'s quantum hardware program and an experimental physicist at the California Institute of Technology.

Scientists can compensate for these high error rates using redundant qubits. However, such strategies often demand high overheads in terms of hardware — for example, they may require more than 1,000 redundant “physical” qubits for every useful “logical” qubit.

Another strategy involves designing quantum computers that are inherently stable against error. Now the AWS Center for Quantum Computing has released a theoretical blueprint for a fault-tolerant quantum computer that intrinsically suppresses a major source of errors.

Skepticism emerges about how far quantum computing has come so far

One of the pioneers of quantum computing warns that industry hype is getting ahead of actual performance. Why it matters: Quantum holds the promise of revolutionizing computing. But there are still enormous hardware and software challenges that need to be overcome.

One-hour coherent optical storage in an atomic frequency comb memory

Photon loss in optical fibers prevents long-distance distribution of quantum information on the ground. Quantum repeater is proposed to overcome this problem, but the communication distance is still limited so far because of the system complexity of the quantum repeater scheme.
