Quantum Computing at the University of Tartu
OpenSuperQPlus ühendab 28 Euroopa teaduspartnerit 10 riigist, kelle eesmärk on arendada välja 1000 kvantbitine kvantarvuti
Käivitub projekt OpenSuperQPlus, mis on osa Euroopa kvanttehnoloogia juhtprojektist. See jätkab ja täiustab projekti OpenSuperQ ning koondab suurema osa meeskonnast uute partneritega – sealhulgas Hollandi, Prantsusmaa, Soome,
Silvério et al., Quantum (2022)
Cold Rydberg atoms in optical lattices are one type of basic quantum systems that are being used for the early stages of quantum computing, e.g., by the French startup Pasqal, the MIT/Harvard spin-off QuEra (whose software is in Julia 👍,
Tune in to the WEF live stream for the quantum computing session:
Speakers including Jeremy O’Brien (PsiQuantum) and Freeke Heijman (Quantum Delta) will discuss questions such as, what should companies and governments be doing now to get ready?
Our paper on Input Redundancy for Parameterized Quantum Circuits was just published by Frontiers in Physics. A good excuse to talk about the no-cloning theorem and its consequence for quantum neural networks.
The No-Cloning theorem states that quantum information cannot be duplicated: There is no mechanism which takes the quantum state of,
To those of us who are familiar with IBM’s devices, the new “Falcon” processors look markedly different. The reason is that the qubit layout is tailored for another quantum error correcting code (arXiv:1907.09528 — not the standard surface code). The orange qubits were used in the experiment; the qubits linked to an R can be read out simultaneously.Over the summer, the following two courses will take place every week (unless there’s a holiday). They are targeted at students of math, physics, computer science who specialize in quantum computing. If you want to come, get in touch! (To be on the mailing list for the the room #s.)

Quantum computing technology is progressing rapidly, but we are not quite there yet. There are several paths through which physicists hope to realize fully-fledged quantum computers. One of them is topological quantum computing which relies on exotic quasi-particles which live in 2 dimensions, so-called anyons.
All fundamental particles are either fermions (example: electrons) or bosons (example: photons).
On June 2 Michael Nitsenko defended his master’s thesis in Quantum Circuit Fusion in the Presence of Quantum Noise on NISQ Devices. In his thesis research, Michael studied a concept called “circuit fusion” which proposes to reduce stochastic noise in estimating expectation values of measurements at the end of quantum computations. But near-term quantum computing devices are also subject to quantum noise (such as decoherence etc),

Abstract.
Topological quantum computing is an approach to building a quantum computer that attempts to cleverly bypass the main obstacles of quantum computers today –
There’s a new article on Wired about quantum computing.
“New” is relative: the article is still chewing the topics of ~4 months ago — a long time for a fast paced field (e.g., the excitement about Majorana zero modes on gold surfaces; background is here).
