A novel algorithm that can characterize topological orders in both prime- and nonprime-dimensional qudit stabilizer codes is introduced. @YijiaXuPhy @IosueJoe @JointQuICS

[Joint Quantum Institute @JQInews]

Researchers at JQI and @JointQuICS have constructed new mathematical tools for continuous variable quantum systems that could lead to more efficient benchmarking for quantum devices (and more!): https://t.co/hQFR9HMW0U @NIST @UMDPhysics @UMDscience

[QuICS @JointQuICS]

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: https://t.co/ZelVn5PLJ9

[Physical Review X @PhysRevX]

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.

Classical shadows are not restricted to qubits if we take them not as a specific technique but as a philosophy of thinking statistically. (1/7)

[Joseph Iosue @IosueJoe]

We establish a relation between average and entanglement fidelities for CV operations that generalizes the corresponding relation in finite dimensions. The dimension factor is replaced by an effective dimension that depends on the mean energy of the input state. [6/6]

[Joseph Iosue @IosueJoe]

Do quantum t-designs exist in infinite dimensions? In our new paper, we study continuous-variable (CV) t-designs and applications thereof.

We then regularize rigged designs, leading to a notion of approximate energy-constrained CV designs. Using regularized 2-designs, we define the average fidelity of a CV quantum channel, and employ these formulas to quantify the performance of a displacement operation. [5/6]

New paper on Variational Quantum Simulation! Congrats to our former summer students Cristina, Zoe, and @IosueJoe . Our algorithm allows for “fast-forwarding” (long-time simulation with fixed circuit depth). Rigorous error analysis is provided. https://t.co/yyNUShD1Jz

[Patrick Coles @ColesThermoAI]

QAQC (pronounced Quack), a variational algorithm for compiling, is now published. Congrats to our summer students and future stars @SumeetKhatri6, @aporemba_ and @ryanmlarose for authoring the first-ever paper from the LANL Quantum Computing Summer School https://t.co/JBmEuDPMut

[Will Zeng @wjzeng]

https://t.co/FG3fC3RRet 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: https://t.co/5Ljr5MQLrP

[Will Zeng @wjzeng]

This update also includes a new grant to the NISQAI project to build a library for machine learning with near-term quantum processors.
