Happy to introduce PastaQ, a Julia package for simulating and benchmarking near-term #quantum computers, using a combination of tensor networks and #MachineLearning algorithms. github.com/GTorlai/PastaQ.jl Really fun project with Matt Fishman @FlatironCCQ, supported by @SimonsFdn.

In our latest work, we introduce an active learning 🤓 scheme to efficiently reconstruct a quantum state ⚛️ by choosing the measurement configurations adaptively — check out the details here: arxiv.org/abs/2203.15719 @QManyBody @MKebric @harvardphysics @MCQST_cluster

Roeland Wiersema's new preprint: if your quantum algorithm uses a small number of gates that can't be physically implemented, you can emulate their action classically through measurement and re-preparation on the qubits where the gates act arxiv.org/abs/2203.04984

Your RNN-based VMC needs long runtimes to converge? Speed it up with a data-driven initialization! Check out our preprint to see how a small amount of measurement data can significantly improve the performance of VMC: arxiv.org/abs/2203.04988 @MossSchuyler @MRadzihovsky @rgmelko

Check out my new preprint: arxiv.org/abs/2202.05850 Stripe formation in systems of strongly interacting electrons can lead to a "fragmentation" of the superconducting condensate.

Fragmented Cooper pair condensation in striped superconductors

Condensation of bosons in Bose-Einstein condensates or Cooper pairs in superconductors refers to a macroscopic occupation of a few single- or two-particle states. A condensate is called...

Running quantum-classical workloads in the @awscloud just became a lot easier and more performant. With today’s launch of Amazon Braket Hybrid Jobs, you just need to provide your algorithm, and Braket will take care of the rest. Try it out today bit.ly/HybridJobs

New preprint in collaboration Roeland Wiersema, Cunlu Zhou, and Yong-Baek Kim. We provide evidence that variational quantum circuits display measurement induced entanglement transitions. Also interspersed measurements could alleviate barren plateaus scirate.com/arxiv/2111.08035

Amazon joins race for quantum computer with new Caltech center

The investment reflects growing corporate interest in quantum computers, which are still at an early stage of development but could someday crack problems that existing computers can’t.
