“Nearly nine years after we started, we have pushed the technology to an unprecedented level of maturity and performance” said Pete Shadbolt, PsiQuantum cofounder and Chief Scientific Officer. “We have the chips, we have the switches, we have a scalable cooling technology, we can do networking, we have found the sites, we have the commercial motive and the government support—we’re ready to get on and build utility-scale systems.”https://arxiv.org/html/2404.17570v1 26 Apr 2024 A manufacturable platform for photonic quantum computing with photons Global Foundries Has switches.

“Alice & Bob is a quantum computing company based in Paris and Boston whose goal is to create the first universal, fault-tolerant quantum computer. Founded in 2020, Alice & Bob has already raised €130 million in funding, hired over 150 employees and demonstrated experimental results surpassing those of technology giants such as Google or IBM. Alice & Bob specializes in cat qubits, a pioneering technology developed by the company’s founders and later adopted by Amazon. Demonstrating the power of its cat architecture, Alice & Bob recently showed that it could reduce the hardware requirements for building a useful large-scale quantum computer by up to 200 times compared with competing approaches.”
Wilson Sonsini on IP strategy for quantum “We’re seeing a shift from research-heavy moonshots to more application-oriented investments—companies developing near-term commercial use cases like quantum sensing, quantum-secure communications, and hybrid AI systems. VC interest will likely follow the path we saw with AI: from foundational tools to vertical-specific applications. Expect to see more funding into enabling technologies, such as cryogenic systems, photonics, and error-correction software.”
Phasecraft Quantum algorithms https://www.phasecraft.io/ for simulation Funding https://www.phasecraft.io/news/phasecraft-raises-34-million-from-plural-playground-novo The company’s core business is to design quantum algorithms that significantly reduce the hardware requirements—such as the number of qubits and circuit depth—needed to solve complex problems, thereby accelerating the timeline to achieving quantum advantage. Phasecraft’s revenue model is centered on partnerships with both quantum hardware manufacturers and companies in various industries that stand to benefit from quantum computation. By collaborating with hardware leaders like Google, IBM, Rigetti, Quantinuum, and QuEra, Phasecraft gains access to the most advanced quantum processors to test and refine its algorithms. “Our algorithms are delivering meaningful results now, whether it’s simulating the physics of complex materials or optimizing the structure of a large energy network “
