Scientists at EPFL in Lausanne, Switzerland, have built the first ever chip-integrated erbium-doped waveguide laser that approaches the performance with fiber-based lasers, combining wide wavelength tunability with the practicality of chip-scale photonic integration. The breakthrough is published in Nature Photonics.

Researchers at ETH Zurich have shown that quantum states of single electron spins can be selectively manipulated using spin-polarized currents (electronic currents with uniformly aligned spins). Unlike electromagnetic field manipulation, spin-polarized currents act very locally and can be steered with a precision of less than a nanometre. Therefore, this current can precisely manipulate electronic circuit elements in quantum devices, offering improved control of the quantum states of magnetic qubits.

The quantum researchers at the École Polytechnique Fédérale de Lausanne (EPFL) have recently secured funding from the ETH-Domain Quantum-Technology Network (QTNet) program to aid them in procuring quantum hardware, enabling further development and application of quantum technologies. It is understood that 12 projects, led by 11 quantum researchers from the university, have been granted funding, with each receiving between CHF 30k to 300k, depending on their specific needs.

SEALSQ, a provider of integrated technology solutions, announced yesterday that it plans to launch two new quantum-resistant chips, the QS7001 and QVault TPM, as early as the fourth quarter of 2024. The company said that these security chips are optimized for Kyber and Dilithium post-quantum cryptographic algorithms. The QS7001 will be open for delivery, allowing customers to develop and load their own firmware, while the QVault TPM comes pre-provisioned with its certified Trusted Platform Module stack.
