NVIDIA Accelerated Quantum Center

NVIDIA announced its new Accelerated Quantum Center to set to open in Boston later this year. Rather than focusing on quantum hardware, the center tackle issues like integration with classical systems, error correction, hardware simulation, and hybrid algorithms.

The center will partner with bold-faced quantum players, including Quantinuum, QuEra Computing, and IonQ — as well as Harvard and MIT.

“What I would love to do is work with NVIDIA researchers and engineers, and have a space where we can go in there and do work together,” MIT’s Will Oliver, and a co-founder of Atlantic Quantum, told MassLive. “There’s a lot of development and improvement and optimization that still has to happen.”

Reuters also covered NVIDIA’s roll-out, with Infleqtion CEO Matt Kinsella saying "We're following a tried and true monetization and market development strategy of monetizing those areas where we actually have true quantum advantage today."

Certified randomness

A multi-institutional team demonstrated certified randomness using a quantum system, then using a classical supercomputer to confirm that the numbers generated are fresh and truly random. The calculations ran on a 56-qubit Quantinuum trapped-ion quantum computer. They were based on a protocol developed in 2018 by the University of Texas at Austin’s Scott Aaronson.

The team also included JPMorganChase, Argonne National Laboratory, and Oak Ridge National Laboratory.

“Building upon the original protocol and realizing it is a first step toward using quantum computers to generate certified random bits for actual cryptographic applications,” Aaronson said.

The study was published in Nature.

Maximally entangled superimpositions

Georgia Tech researchers introduced a new protocol for generating entangled photons, using non-Abelian quantum holonomy, that can be implemented with an on-chip photonic system. The teams calculations indicate that a subset of the generated superpositions are maximally entangled, volume-law states.

“The key discovery here is we can entangle photons in a useful, controllable, and deterministic way,” Aniruddha Bhattacharya, a postdoc on the project, said in an announcement from Georgia Tech.

The study was published in Physical Review Letters.

All-to-all interconnect

An MIT team developed a chiral quantum interconnect that allows for all-to-all communication among non-local nodes. It relies on quantum interference to emit and absorb microwave photons.

“We can send photons at different frequencies, times, and in two propagation directions, which gives our network more flexibility and throughput,” said Aziza Almanakly in an MIT announcement. She is a PhD student and lead author on the study.

The paper appeared in Nature Physics.
