00 🗞 Tech News
Riverlane, a software startup based in Cambridge, UK, raised £ 3 mln in seed funding from UK VCs. Link
Serge Haroche (co-recipient of the 2012 Nobel Prize in Physics): Hype is too high on quantum computers. Link
“The U.S. National Quantum Initiative: From Act to action”. Link
An overview of quantum tech startups in Singapore. Link
“How a quantum computer could break 2048-bit RSA encryption in 8 hours”: This is an advancement in theory results, but it still requires 20 million working qubits, while current platforms for circuit-based computers are implementing tens of them only, at much higher error rates. Link
Microsoft open-sources its quantum computing development tools. Link
IBM is making partnerships for quantum computing research with universities abroad, including in Africa. Link
01 📰 Research Highlights
On superconducting qubits:
- I live-tweeted from the conference marking the 20th anniversary of superconducting qubits. Link
- Cavity quantum electrodynamics with atom-like mirrors. Link
- Phonon-mediated quantum state transfer and remote qubit entanglement. Link
- “Establishing the Quantum Supremacy Frontier with a 281 Pflop/s Simulation.” Scientists at Google Research, Nasa Ames, and US national labs, used the most powerful supercomputer, Oak Ridge’s Summit, to benchmark a calculation that is deemed a feasible milestone for quantum supremacy. This paper seems an instrumental “classical” test for future claims on quantum supremacy. Fun fact: Summit computing processing units are by IBM, but the supercomputer is fitted also with Nvidia GPUs. Link
- Experimental test of non-macrorealistic cat-states in the cloud. Link
- A Quantum Engineer’s Guide to Superconducting Qubits. Link
- Superconducting Qubits: Current State of Play. Link
- Simulating quantum many-body dynamics on a current digital quantum computer. Link
Advances in Quantum Cryptography. Link
Quantum simulation of black-hole radiation. Link
On machine learning:
- Machine learning quantum states in the NISQ era. Link
- Integrating Neural Networks with a Quantum Simulator for State Reconstruction. Link
On photonics analog computers and their learning capabilities (center of the previous newsletter Focus article):
- Photonic Ising Machines Go Big. Link
- All-optical spiking neurosynaptic networks with self-learning capabilities. Link
