BRIEF BYTES

NEWS FOR THOSE IN A HURRY

• The National Science Foundation recently showcased its quantum information technology projects to Congress and emphasized the urgent need for additional funding to support ongoing innovation and maintain global competitiveness. The event demonstrated the benefits of taxpayer-funded research, especially in the quantum sciences, to secure continued investment amid recent budget cuts.

• DigiCert has announced the inaugural World Quantum Readiness Day to be set for September 26, 2024. This initiative encourages businesses and governments to evaluate their quantum readiness and begin integrating post-quantum cryptography standards into their security frameworks. Digicert will also be hosting a digital World Readiness Day event: pre-register here.

• At the upcoming GEOINT Symposium May 5-8, Vibrint will display their latest advancements in national security technology. These include new forms of secure wireless communication, enhanced AI deployments, hybrid cloud platforms, and a product designed to counteract quantum attacks.

• Despite a recent dip in stocks, Rigetti Computing shows promising revenue growth projections and there is a strong buy consensus from analysts. Rigetti is actively expanding its global footprint recently announcing its first quantum system sale in Singapore. Plus, the launch of the Novera QPU Partner Program is further expanding its reach.

NEWS

XANADU AND PARTNERS ARE SECURING CANADA’S SMART GRIDS

The Brief Byte:  Xanadu, together with the University of Toronto, Toronto Metropolitan University, and industry partners, announces a project to integrate quantum technologies, cybersecurity, and deep learning into smart grid applications.

Breakdown:

• The collaboration, supported by a NSERC Alliance-Mitacs Accelerate grant, focuses on cybersecurity for smart grids. This is increasingly important as quantum risks to existing cryptographic systems necessitates the development of quantum-resistant solutions to secure critical infrastructure.

• The project involves the development of algorithms for smart grid devices along with creating cryptographic solutions that secure smart grids by leveraging the combined expertise of academic researchers and industry leaders.

• By aligning with Canada’s National Quantum Strategy and the National Cyber Security Action Plan, the project demonstrates the strategic importance of industry-wide collaboration in working towards a secure national infrastructure.

RESEARCH

DECOHERENCE AS AN UNEXPECTED TOOL FOR HIGH FIDELITY

The Brief Byte: A new study introduces a method for quantum teleportation. Multipartite hybrid entanglement makes use of decoherence in a way that achieves high fidelity in quantum state transfers without the need for entangled qubits to undergo Bell-state measurement.

Breakdown:

• Decoherence reduces the effectiveness of quantum teleportation by degrading entangled states. This has led to extensive efforts in shaping strategies that combat decoherence, including quantum error correction and decoherence-free subspaces. This study proposes a method that not only manages but utilizes decoherence through multipartite hybrid entanglement. This would allow for quantum teleportation under more practical, noisy conditions.

multipartite entanglement: quantum entanglement across more than two subsystems or particles

Check out this chapter from “Modern Quantum Theory” on multipartite entanglement.

Or, this article that thoroughly analyzes the geometry of multipartite entanglement.

Or, the following lecture (featuring a Leonard Susskind cameo) from the Stanford Institute for Theoretical Physics.

• Experimentally, researchers introduce a quantum teleportation protocol that does not require entangled qubits to enter the Bell-state measurement, but instead uses multipartite hybrid entanglement. The protocol was tested in a linear optical setup where phase information was strategically scrambled and reassembled through dephasing.

• Ultimately, the study confirmed that using multipartite hybrid entanglement could retain fidelity of quantum teleportation despite the presence of noise. Decoherence, if strategically managed, may actually be more of a tool and less of a liability which further demonstrates the value of challenging our traditional views around noise and decoherence in the search for fault-tolerance.
