Today’s Brief Commentary:
Today, I am directing my remarks toward quantum computing companies, particularly small ones. Many of your websites need work. Here are a few suggestions:
- Be explicit about your quantum computing modality and paradigm. For example: “We implement the digital paradigm using neutral atom qubits.”
- Say you support specific quantum software development kit (SDK) such as Cirq, Qiskit, or a home-grown tool collection. Be exhaustive in the list of SDKs you support. Be transitive: if you support Qiskit and I can use Pennylane to generate Qiskit code, say you support Pennylane.
- If you have your own SDK but provide no details about it, don’t bother mentioning it,
- I might wander away if your flashy welcome animation goes on too long and I can’t see information about your company.
- Test that animation with a few friends to see if it makes them feel seasick.
- Consider listing your senior leadership team and including links to their LinkedIn profiles. You get extra points if their LinkedIn profile role descriptions match what you say on your website.
I have more ideas in this vein, but that’s enough for now.
Don’t forget to check out and bookmark my new sortable list of upcoming quantum technology conferences.

Advancing quantum technology in Japan: AIST and IQM join forces
Date: Wednesday, December 18, 2024
Commentary: Okay, I missed this in December. We can now add IQM to the list of quantum companies working with partners in Japan including, IBM, Infleqtion, Quantinuum, and QuEra. In particular, see the next link about Quantinuum and RIKEN.
Excerpt: The National Institute of Advanced Industrial Science and Technology (AIST) and IQM Quantum Computers (IQM), a global leader in superconducting quantum computers, have signed a Memorandum of Understanding (MOU) to strengthen collaboration for the industrialisation of quantum technology in Japan.
Quantinuum’s “Reimei” Quantum Computer Now Fully Operational at RIKEN, Ushering in a New Era of Hybrid Quantum High-Performance Computing
Date: Wednesday, February 12, 2025
Excerpt: Quantinuum, the world’s largest integrated quantum computing company, and RIKEN, Japan’s largest comprehensive research institution, today announced the successful on-premise installation of Quantinuum’s “Reimei” quantum computer at RIKEN’s Wako campus in Saitama, Japan. RIKEN has designed, prepared, and delivered a world-class facility for the trapped-ion quantum computer, which will enable generations of high-performance quantum systems.

Quantum and Security: Fact or Fiction? – Report Summary | The Futurum Group
https://futurumgroup.com/press-release/quantum-and-security-fact-or-fiction-report-summary/
Author: Dr. Bob Sutor
Date: Thursday, February 13, 2025
Excerpt: As public focus on quantum computing has grown over the years, there has only been one “bad” potential application of the technology: security. Will we ever have a big and powerful enough quantum computer to break encryption/decryption protocols such as RSA? Are there new cryptography standards that will be unhackable by quantum systems? If so, which companies are implementing them? Can quantum tech be used for “good” security applications?

Infleqtion Demonstrates Largest Neutral Atom Array in UK, Paving Way for Scalable Quantum Computing
Date: Tuesday, February 18, 2025
Excerpt: As part of this collaboration, Infleqtion has demonstrated scalable atom trapping in 16×16 arrays at the NQCC’s Harwell Science and Innovation Campus, setting the stage for the next phase of development. The team is also integrating advanced gate laser systems to enable full quantum logic operations, aligning with the UK’s goal of establishing a 100+ qubit quantum computing capability at NQCC by 2025.

The formation of a nuclear-spin dark state in silicon | Nature Physics
https://www.nature.com/articles/s41567-024-02773-w
Authors: Xinxin Cai; Habitamu Y. Walelign; and John M. Nichol
Date: Tuesday, January 28, 2025
Commentary: See the more general news article below.
Excerpt: Silicon-based qubits are often made by trapping individual electrons in quantum dots defined by electric gates. Quantum information can then be stored using the spin states of the electrons. However, the nuclei of the surrounding atoms also have spin degrees of freedom that couple to the electron-spin qubits and cause decoherence. The emergence of a nuclear-spin dark state has been predicted to reduce this coupling during dynamic nuclear polarization, when the electrons in the quantum dot drive the nuclei in the semiconductor into a decoupled state. Here we report the formation of a nuclear-spin dark state in a gate-defined silicon double quantum dot. We show that, as expected, the transverse electron–nuclear coupling rapidly diminishes in the dark state, and that this state depends on the synchronized precession of the nuclear spins. Moreover, the dark state significantly reduces the relaxation rate between the singlet and triplet electronic spin states. This nuclear-spin dark state has potential applications as a quantum memory or in quantum sensing, and might enable increased polarization of nuclear-spin ensembles.

Author: Lindsey Valich
Date: Wednesday, February 12, 2025
Excerpt: Because nuclear-spin dark states are very stable, they could be used in quantum computers and other technologies to store information long-term. They could also be used to make incredibly exact measurements by detecting tiny changes in magnetic fields, temperature, or pressure, improving medical imaging and navigation.
Quantum Error Correction and Fault Tolerance
IQM, Riverlane, and Zurich Instruments join forces to launch world’s first quantum error correction platform
Date: Thursday, February 6, 2025
Commentary: Interesting plan, but not sure about the name. It would be good to see a six month update at the beginning of August to learn about their progress. A+ grade for partnership.
Excerpt: IQM Quantum Computers, Riverlane, and Zurich Instruments have announced the launch of the SurgeonQ project, a strategic collaboration to create the first quantum computing platform capable of running multiple real-time quantum error correction operations. The project represents progress towards commercially viable quantum computing systems.
