CEA, in collaboration with CNRS Néel, a team in SI-based quantum computing, presented two papers on that topic at IEDM 2021, including an invited paper that identifies the material and integration challenges facing large-scale Si quantum computing.

While the number of qubits and the stability of quantum states are still limiting current quantum computing devices, there are questions where these processors are already able to leverage their computing power.

Xanadu and imec have announced a partnership to develop the next-gen of photonic qubits based on ultra-low loss silicon nitride (SiN) waveguides, the partnership is to fabricate low loss and uniform silicon nitride circuits for error corrected qubits. 

Keysight Technologies has added to its quantum portfolio with the acquisition of Quantum Benchmark, a supplier of error diagnostics, error suppression and performance validation software for quantum computing. 

How do you determine what is going on when you can’t actually see the components in the system you are investigating? This is the challenge when investigating the quantum behaviour of electrons in a lattice of ions. The solution being created by the Physics Department at the University of San Diego, California is to build a model that is slightly larger with observable components of single atoms moving in an optical lattice.

Launched in late 2018, Nu Quantum recently became an Associate Member of the EU-funded Graphene Flagship project. The startup, a spin off from the Cavendish Laboratory at Graphene Flagship partner the University of Cambridge, UK, specialises in single-photon quantum technology that is set to create unbreakable encryption keys.

Sectigo has announced the launch of Sectigo Quantum Labs to help organizations prepare for the time when quantum computers render existing standard encryption algorithms obsolete. As part of the company’s quantum initiative, Sectigo has partnered with ISARA Corporation to provide enterprises with tools for issuing quantum-safe certificates for users, applications, servers, DevOps, code, and more. Sectigo’s Quantum-Safe Toolkit Ce...

Leti, an institute of CEA, has created a quantum integrated circuit that demonstrates the possibility of integrating conventional electronic devices and elements with quantum dots on a CMOS chip. 

Fujitsu Laboratories, has shown the capability of the Digital Annealer to maximise the performance of magnetic devices essential for renewable energy harvesting and other uses. The application of Fujitsu's next-generation architecture allows for the nearly instantaneous calculation of the optimal arrangement of multiple planar (2D) magnets to maximise the strength of the magnetic field in a device.

  It has been announced that HORIBA Scientific has developed for QuantIC, the UK Quantum Technology Hub in Quantum Enhanced Imaging, Time-Correlated Single-Photon Counting (TCSPC) electronics to support its research into real-time computational 3D imaging and Light Detection And Ranging (LiDAR).
