unitary.fund has had a great first few months making grants for open source quantum computing projects. Congratulations to these projects (from compilers to quantum machine learning libraries) in our first quarterly update: medium.com/@wjzeng/unitar…

This update also includes a new grant to the NISQAI project to build a library for machine learning with near-term quantum processors. Proposal: github.com/QuantumAI-lib/… Video: youtube.com/watch?v=_dOJ7B… Congrats to the team! Ryan LaRose

This is the QC Ware team working towards practical, near-term speed-ups for quantum algorithms. A Jacobi Diagonalization and Anderson Acceleration Algorithm For Variational Quantum Algorithm Parameter Optimization - arxiv.org/abs/1904.03206

QAQC (pronounced Quack), a variational algorithm for compiling, is now published. Congrats to our summer students and future stars Sumeet Khatri, Alexander Poremba and Ryan LaRose for authoring the first-ever paper from the LANL Quantum Computing Summer School quantum-journal.org/papers/q-2019-…

New paper on Variational Quantum Simulation! Congrats to our former summer students Cristina, Zoe, and Joseph Iosue . Our algorithm allows for “fast-forwarding” (long-time simulation with fixed circuit depth). Rigorous error analysis is provided. scirate.com/arxiv/1910.042…

Quantum t-designs - ensembles of states that mimic uniform averaging - for infinite-dimensional spaces do not exist, but an alternative “rigged t-design” is possible. Read go.aps.org/3HRNIVF Joseph Iosue Kunal Sharma Victor V. Albert #PRXqst #PRXjustpublished #openaccess

Our researchers have constructed a new mathematical shortcut—called continuous variable quantum state design—that expands previous tools to a new realm where quantum measurements can yield an infinite number of possible values like a continuum. Learn more: go.umd.edu/3P9wuY3
