Another day another paper by one of my (now former) colleague, myself and a few others on the feasibility of #quantumcomputing and #quantumalgorithms

If you are interested in such things, please check it out. I am also very keen to learn about your possible experiences on applying quantum computing. We are now researching the #cybersecurity of quantum computing in a couple of different projects.

Posted today: strategies for how to go about optimising double-bracket #quantumAlgorithms
https://scirate.com/arxiv/2408.07431

We compare with cases inspired by Brockett's #doubleBracketFlow which have rigorous global convergence guarantees and found that departing from them and at every step optimising the involved generators gives faster diagonalization.

This motivates our upcoming work on training our double-bracket circuits on single-shot samples: today we posted that 1) within the class of #doubleBracket #quantum algorithms it's worthwhile to variationally train the parametrisations at every step, last week we posted that 2) warm-starts from #VQE facilitate very high ground state preparation fidelity and so 3) training on shot-noise limited data will give an idea how to use our approach on future large-scale quantum hardware.

. In panel a) we show DBRs for the analytically motivated ansatze. The GWW parametrization
yields the largest
σ-decrease. Bullets indicate the first local minima extracted numerically. In panel b) we show DBRs for parametrizations which can be easily compiled using CNOT and single-qubit rotation gates. Here the global minimum is not necessarily the first. The GWW curve is repeated because it coincides with the NN Ising strategy. In panels c) and d) we show the respective BHMM iteration. We stop, for each adopted strategy, the DBI steps when they would have provided only marginal gain at the expense of long evolutions. Due to the symmetries of XXZ the GWW and magnetic field strategies yield block-diagonalization as opposed to full diagonalization. In panel d) for short
s
the local
parametrization strategies perform comparably well with those in panel c). These results set the benchmark when moving from analytically prescribed BHMM DBIs to adaptive DBIs.

We have a TT Assistant Professor position in Quantum Algorithms for Chem & Life Science open at UCPH. Please apply! Encourage your friends to apply. Extended deadline August 20.

I know there are lots of quantum folks on Mastodon (because I enjoy reading all your posts 😀 ) - we'd really appreciate boosts to try to get this out to a broader quantum audience.

DESY Ukraine Winter School "Introduction to Quantum Computing" lecture by Dr. Stefan Kühn on Enabla

#Combinatorialoptimization - a field of research addressing problems that feature strongly in a wealth of practical and industrial contexts - has been identified as one of the core potential fields of applicability of near-term #quantumcomputers. It is still unclear, however, to what extent variational #quantumalgorithms can actually outperform classical algorithms for this type of problems.

@MarisOzols I don't know anything about #QuantumAlgorithms, so the image looks like a medieval music sheet to my eyes
🙃

#pointofview

#QuantumAlgorithms can be beautiful to look at! Here is a #quantum circuit on 68 qubits that prepares the ground state of a certain Hamiltonian that corresponds to a quantum error correcting code.

This can be used to simulate the behavior of certain exotic particles called non-Abelian anyons.

In Episode 4, we talked to Prof. Román Orús about #TensorNetworks, #QuantumAlgorithms and #QuantumInspired techniques.

We heard about how algorithms that originated in many-body physics could be put to use in solving real-world optimisation problems and how #MultiverseQC is applying these techniques with real clients in areas such as finance.

Take a listen to the episode if you'd like to know more - available on all good podcasting platforms!
