Credit: IBM IBM's Research in qLDPC Codes The popular press is buzzing with IBM's announcement that they have published an article about the research of qLDPC (Quantum Low Density Parity Check) codes in Nature magazine. But attentive readers of the Quantum Computing Report will note that we first reported about this last August when the preprint of this paper describing this research was first posted on the arXiv and again this last December in our article about IBM's roadmap. LDPC codes are a [...]

Credit: Journal of Physical Chemistry Chemical Physics If you had asked us six months ago, when we thought fault tolerant quantum computers would become available, we would have estimated some time around the 2030 timeframe. We would have indicated that between now and 2030, available quantum computers would all be NISQ based and that a few users would be able to figure out how to use these NISQ machines to achieve quantum advantage for a few applications during this period. But over the past few months, we have seen a large number of technical papers and roadmaps that indicate what we [...]

Progress report three years after the launch of the national strategy for quantum technologies and launch of the PROQCIMA program In a bid to make France the center of gravity of the global quantum industry, the government has launched a French National Strategy for quantum that included projected investments of €1 billion ($1.1B USD) from the government over a four year period with additional investments being made by the private sector. France has made considerable progress is enjoying significant quantum startup activity and private funding in the country as well as gains in attracting and developing talent. To further accelerate progress [...]

By Prof Michael J Biercuk, CEO and Founder, Q-CTRL Excitement about the era of Quantum Error Correction (QEC) is reaching a fever pitch. This has been a topic under development for many years by academics and government agencies as QEC is a foundational concept in quantum computing.  More recently, industry roadmaps have not only openly embraced QEC, but hardware teams have also started to show convincing demonstrations that it can really be implemented to address the fundamental roadblock for quantum computing - hardware noise and error. This rapid progress has upended notions that the sector could be stagnating in so-called NISQ [...]

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 [...]
