Insider Brief Venture capital is currently focused on turning a quick buck, not long-term investments, according to MIT Sloan Management Review columnists. In the past VCs funded cutting-edge, but risky companies and technologies. The piece […]
Qubits are the building block for quantum technology, and finding or building qubits that are stable and easily manipulated is one of the central goals of quantum technology research. Scientists have found that an atom […]
About 70 years ago, an engineer at IBM named Hans Peter Luhn quietly changed the course of computer science. Luhn already held several patents, including one for a device that could measure a cloth’s thread […]
Since early demonstrations of femtosecond laser as a three-dimensional (3D) processing tool, microdevices with exciting optical, electronic, mechanical, and magnetic functions have been manufactured, by which novel concepts from 3D quantum photonic integrated circuits to […]
In quantum sensing, atomic-scale quantum systems are used to measure electromagnetic fields, as well as properties like rotation, acceleration, and distance, far more precisely than classical sensors can. The technology could enable devices that image […]
Quantum 8, 1245 (2024). https://doi.org/10.22331/q-2024-02-08-1245 We present a generalized framework to adapt universal quantum state approximators, enabling them to satisfy rigorous normalization and autoregressive properties. We also introduce filters as analogues to convolutional layers in […]
Quantum 8, 1244 (2024). https://doi.org/10.22331/q-2024-02-08-1244 We present an analytical method to estimate pure quantum states using a minimum of three measurement bases in any finite-dimensional Hilbert space. This is optimal as two bases are insufficient […]
Insider Brief Nord Quantique demonstrated quantum error correction to improve qubit coherence lifetime at the individual qubit level. The research shows an increase of 14% in the lifetime of a single qubit without using the […]
Testing and benchmarking are crucial steps in adopting and commercialising technologies. In the rapidly emerging world of quantum computing, where complexity and novelty present formidable challenges, the role of rigorous testing and benchmarking becomes not […]
Unrelated Announcement (Feb. 7): Huge congratulations to longtime friend-of-the-blog John Preskill for winning the 2024 John Stewart Bell Prize for research on fundamental issues in quantum mechanics! On the heels of my post on the […]
