Shown below are summaries of a few interesting research papers in quantum technology that we have seen over the past month. Hardware Title: Quantum control of a cat-qubit with bit-flip times exceeding ten secondsOrganizations: Alice & Bob, Laboratoire de Physique de l’Ecole normale superieure, ENS-PSL, CNRS, Sorbonne Universite, UniversiteParis Cite, Centre Automatique et Systemes, Mines Paris, Universite PSL, Inria, Ecole Normale Superieure de Lyon, CNRS, Laboratoire de PhysiqueThis paper describes an implementation of a cat-qubit with bit-flip times exceeding ten seconds which is a four order of magnitude improvement over previous cat-qubit implementations, and six orders of magnitude enhancement over the single [...]

The OpenSuperQPlus program is a successor to the previous OpenSuperQ program that will be coordinated by Forschungszentrum Jülich GmbH and involve 28 partners from 10 different countries. It has a first stage goal of developing a 100 qubit system within 3.5 years and a second stage goal of developing a 1000 qubit system within seven years. The funding will come from the European Union's Horizon Europe framework program. A press release announcing the program can be seen on the Forschungszentrum Jülich website here and a list of all the partners in the program are shown below.

By Dr Chris Mansell, Senior Scientific Writer at Terra Quantum Shown below are summaries of a few interesting research papers in quantum computing and communications that we have seen over the past month. Software Title: Fault-Tolerant Connection of Error-Corrected Qubits with Noisy LinksOrganizations: MIT-Harvard Center for Ultracold Atoms and Research Laboratory of Electronics; University of BristolQubit architectures are hard to scale: ions experience spectral crowding of their motional modes, superconductors have to fit inside a cryostat and arrays of ultracold atoms must stay within the field of view of an aspheric lens. One way to overcome this is to link patches [...]

The performance of today’s quantum hardware remains modest, and despite the hard work of innovators that is not going to change overnight. Each qubit platform faces its own significant challenges as vendors seek to scale up. But if we look at the details we can see that underlying progress remains strong across the hardware stack. Progress on error correcting codes must not be neglected. Innovation there has the potential to disrupt our standard assumptions about what it takes to build a quantum computer. The strategic [...]
