The Beginnings Of the four major US-founded players in the quantum computing (QC) market consisting of Google, IBM, Microsoft, and AWS Braket (Amazon), only IBM has a legacy in technological innovation that stretches back more […]
Quantum 6, 754 (2022). https://doi.org/10.22331/q-2022-06-30-754 We give a classical algorithm for linear regression analogous to the quantum matrix inversion algorithm [Harrow, Hassidim, and Lloyd, Physical Review Letters’09] for low-rank matrices [Wossnig, Zhao, and Prakash, Physical […]
Quantum 6, 753 (2022). https://doi.org/10.22331/q-2022-06-30-753 We present a formalism that captures the process of proving quantum superiority to skeptics as an interactive game between two agents, supervised by a referee. Bob, is sampling from a […]
Quantum 6, 752 (2022). https://doi.org/10.22331/q-2022-06-30-752 Quantum finite automata (QFA) are basic computational devices that make binary decisions using quantum operations. They are known to be exponentially memory efficient compared to their classical counterparts. Here, we […]
By Andre Saraiva, Diraq For the impatient reader, here are the oversimplified answers to the questions we aim to address in this article: “How do I put a price to quantum computation?” The resources needed […]
How do you teach mathematics to an artificial intelligence? AI has already bested humans at problem-solving tasks that include games like chess and Go. But before any task can be tackled by a machine, it […]
Munich based planqc is a spinout from the Max-Planck-Institute of Quantum Optics and Ludwig-Maximilians-University Munich that is developing a room temperature quantum computer based on neutral atoms trapped in optical lattices. The financing round was […]
Levitated nanoparticles are promising tools for sensing ultra-weak forces of biological, chemical or mechanical origin and even for testing the foundations of quantum physics. However, such applications require precise position measurement. Researchers at the Department […]
It sounds like one of the easiest experiments possible: Take two cups of water, one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder […]
Sensing with levitated nanoparticles has so far been limited by the precision of position measurements. Now, researchers have demonstrated a new method for optical interferometry in which light scattered by a particle is reflected by […]
