Whilst holding great promise for low noise, ease of operation and networking, useful photonic quantum computing has been precluded by the need for beyond-state-of-the-art components, manufactured by the millions. Here we introduce a manufacturable platform for quantum computing with photons. We benchmark a set of monolithically-integrated silicon photonics-based modules to generate, manipulate, network, and detect photonic qubits, demonstrating dual-rail photonic qubits with 99.98% ± 0.01% state preparation and measurement fidelity, Hong-Ou-Mandel quantum interference between independent photon sources with 99.50% ± 0.25% visibility, two-qubit fusion with 99.22% ± 0.12% fidelity, and a chip-to-chip qubit interconnect with 99.72% ± 0.04% fidelity, not accounting for loss. In addition, we preview a selection of next generation technologies, demonstrating low-loss silicon nitride waveguides and components, fabrication-tolerant photon sources, high-efficiency photon-number-resolving detectors, low-loss chip-to-fiber coupling, and barium titanate electro-optic phase shifters. - PsiQuantum #quantumcomputing #computing #light #photonics #manufacturing #chip #semiconductors #mathhttps://lnkd.in/e7ZNgiEW

imec announces the demonstration of high-quality 300mm-Si-based quantum dot spin qubit processing with devices resulting in a statistically relevant, average charge noise of 0.6µeV/√Hz at 1Hz. By demonstrating these values, repeatedly and reproducibly, this work makes large-scale quantum computers based on Si quantum dots a realistic possibility Read the full PR: https://ow.ly/zG6550SIRSE #quantum #innovation #qubits

I am delighted that the PDK strength cryogenic compact models developed by Semiwise in the framework of the Innovate UK Cryogenic CMOS consortium: https://lnkd.in/eemaJMw6 have enabled the development of the Surecore IP. This has been done in close collaboration with Synopsys using the Synopsys TCAD and DTCO tools.

UNSW and Diraq quest for scalable hole-spin qubits UNSW Sydney in association with quantum computing start up Diraq have reached a milestone in the hunt for the perfect quantum computing storage qubit to allow faster and more efficient quantum computing applications. The team demonstrated hole-spin qubits – positively charged particles in semiconductors – using industry standard silicon manufacturing processes. Hole-spins qubits have the potential to revolutionise quantum computer data storage by offering rapid operation speeds and seamless integration with existing silicon technology. #manufacturing #quantumcomputing @diraqQC Diraq https://lnkd.in/gcjZkBFk

Programmable Approach To Fabricating Optical Qubits In Silicon Could Lead To Large-Scale Manufacturing ❗ Key highlights: 🔹 Researchers say they are the first to use a femtosecond laser to create and “annihilate” qubits on demand. 🔹This could help quantum computers that use programmable optical qubits or “spin-photon qubits” to connect quantum nodes across a remote network. 🔹The new method uses a gas environment to form programmable defects called “color centers” in silicon. https://lnkd.in/eksyXm-5 #Quantum #Qubits #Sillicon #QuantumComputing

sureCore & Sarcina Work Together on Cryo Chip Packaging Benefiting from Innovate UK funding, cryogenic embedded IP vendor sureCore Ltd has entered into a technology partnership with packaging specialist Sarcina Technology LLC. This has resulted in the realisation of a custom package design that can cope with the ultra-low temperature levels needed for quantum computing. It means that companies in this sector will have the foundation needed for them to create their own cryo-CMOS SoC devices.   According to Paul Wells, sureCore’s CEO; “This represents another critical step in our program to make cryo-CMOS available for the quantum computing ecosystem. Our CryoMem range of memory IP is silicon proven in addition to validating our library recharacterization service. We are also offering a range of cryogenic design capabilities to help quantum computing companies design the control/interface chips which need to be migrated into the cryostat alongside the qubits. Reliable, robust, cryo-ready chip packaging is a necessity in these harsh, low temperature environments - and to ensure this we partnered with Sarcina whose specialist package design expertise is second to none.”   Larry Zu, Ph.D., CEO of Sarcina adds; “We have developed a reputation as the...

One of this year’s standout moments came fromConScience AB, a Gothenburg-based company that launched Sweden’s first fully designed and manufactured commercial quantum device:Qubit-in-a-Box (QiB0). The QiB0 is designed to demonstrate key quantum processes likedecoherenceanddephasing, while also calibrating and verifying quantum setups. Featuring4 qubitsand2 resonatorswith impressive performance metrics, it’s a valuable tool for researchers, universities, and industry professionals. CEO Joachim Fritzsche shared:“Quantum device manufacturing is very complex, and today our hard work pays off.” https://lnkd.in/eByp_XRM #QuantumComputing #Innovation #Qubits #TechNews
