Quantum Computers Enter Data Centers – IEEE Spectrum
https://spectrum.ieee.org/quantum-data-center
(Monday, July 29, 2024) “Data centers and high performance computing clusters around the world are starting to incorporate quantum hardware. But colocating such different technologies and getting them to work together is no easy task. The quantum hardware struggles in a noisy data center, doesn’t naturally fit in with software architecture, and there is a technical language barrier between quantum and classical computing engineers.”

Author: Marie Keane
(Monday, July 29, 2024) “Executive Summary The financial industry depends on secure messaging in transactions sent between banks, merchants, customers, and government agencies; credit card authorizations; wire transfers; account information; and other types of communications. The monetary and systemic value of financial messaging makes it especially vulnerable to cybersecurity attacks. Cryptography is therefore central to trust in the financial Read more…”
Podcast with David Shaw, Chief Analyst at Global Quantum Intelligence – Quantum Computing Report
Author: Doug Finke
(Tuesday, July 30, 2024) “In his role as Chief Analyst at Global Quantum Intelligence, David Shaw combines a PhD in physics with years of advising executives in tech, healthcare, energy, and financial services. This understanding of quantum mechanics and the technology life cycle gives him a unique perspective on quantum hardware. In this episode, he explains how many “chips” it will take to build a quantum computer, how far we are from modularity, and why quantum sensing should get more attention. Transcript Veronica: Hello, and welcome to The Quantum Spin by HKA. I’m Veronica Combs. I’m a writer and an editor here at the agency. I […]”
D-Wave – D-Wave Announces Roadmap to Extend Leap Quantum Cloud Service for AI/ML
“Including support for quantum-enhanced and energy efficient AI model training as well as integrating AI and optimization to address important customer use cases D-Wave Quantum Inc.

[2405.11140] Microstructured optical fibres for quantum applications: perspective
https://arxiv.org/abs/2405.11140
Authors: McGarry, Cameron; Harrington, Kerrianne; Davis, Alex O. C.; Mosley, Peter J.; Rusimova, Kristina R.
(Saturday, May 18, 2024) “Recent progress in the development and applications of microstructured optical fibres for quantum technologies is summarised. The optical nonlinearity of solid-core and gas-filled hollow-core fibres provides a valuable medium for the generation of quantum resource states, as well as for quantum frequency conversion between the operating wavelengths of existing quantum photonic material architectures. The low loss, low latency and low dispersion of hollow-core fibres make these fibres particularly attractive for both short- and long-distance links in quantum networks. Hollow-core fibres also promise to replace free-space optical components in a wide range of atomic experiments.”
Fast, universal scheme for calibrating microwave crosstalk in superconducting circuits | Applied Physics Letters | AIP Publishing
“A challenge in building large-scale superconducting quantum processors is the precise control and manipulation of the qubit state. However, the crosstalk between the microwave control lines impedes the parallel execution of high-fidelity digital and analog quantum operations. Here, we propose and demonstrate a universal compensation protocol for calibrating the microwave signal crosstalk. We also introduce amplified error sequences to optimize accuracy. Furthermore, we show a definitive improvement in parallel gate operations with crosstalk cancellation, demonstrating the technique’s effectiveness. This work paves the way for superconducting hardware that features the automated calibration of microwave crosstalk, leading to enhanced fidelities in multiqubit circuits.”
