Quantum 5, 544 (2021). https://doi.org/10.22331/q-2021-09-16-544 Self-testing is a method to characterise an arbitrary quantum system based only on its classical input-output correlations, and plays an important role in device-independent quantum information processing as well as […]
Back in 2000, when Michael Elowitz of the California Institute of Technology was still a grad student at Princeton University, he accomplished a remarkable feat in the young field of synthetic biology: He became one […]
Spin waves, or magnons, as the elementary excitation of the magnetic system, can transfer spin angular momentum, which provides wide prospects for the Non-volatile, low-energy-consumption, high-speed and small-size microelectronic devices in the post-Moore period. Magnonics, […]
Quantum 5, 543 (2021). https://doi.org/10.22331/q-2021-09-16-543 We give new quantum algorithms for evaluating composed functions whose inputs may be shared between bottom-level gates. Let $f$ be an $m$-bit Boolean function and consider an $n$-bit function $F$ […]
Researchers from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, together with international collaborators, observed an obvious enhancement in the yield ratio between strange (Ds±) and nonstrange (D0) […]
We are looking for highly motivated candidates with a strong research background and a PhD in quantum information with a focus on quantum algorithms. Past work in quantum algorithm design and/or quantum machine learning and/or […]
Over the past year we have reported (here and here) about IBM’s development of an enhanced quantum assembly language called OpenQASM3. Versions of OpenQASM has been used with IBM’s Qiskit from the very beginning and […]
This Erev Yom Kippur, I wish to repent for not putting enough quantum computing content on this blog. Of course, repentance is meaningless unless accompanied by genuine reform. That being the case, please enjoy the […]
Quantum 5, 542 (2021). https://doi.org/10.22331/q-2021-09-15-542 This paper studies the application of the Quantum Approximate Optimization Algorithm (QAOA) to spin-glass models with random multi-body couplings in the limit of a large number of spins. We show […]
Réunion, a French island in the western Indian Ocean, is like a marshmallow hovering above the business end of a blowtorch. It sits above one of Earth’s mantle plumes — a tower of superheated rock […]
