The rate at which quantum computing is hitting the media stream is ever-increasing. This piece is a collection of recent articles and reports covering various aspects of quantum computing from the lens of technology and hardware. Mea Cubitt 

Google Gets One Step Closer to Error-Corrected Quantum Computing | One of the biggest barriers standing in the way of useful quantum computers is how error-prone today’s devices are. Now, Google has provided an experimental demonstration of how to correct this problem and scale it up for much larger devices.  Source: SingularityHub.   Google Gets One Step Closer to Error-Corrected Quantum Computing…

Optical Power Limiter Pushes Attack-Proof Quantum Communication Forward | Researchers from the National University of Singapore (NUS) developed two methods to enable quantum key distribution (QKD) communications to avoid side-channel attacks — instances in which attackers exploit weaknesses in the setup of the information system to eavesdrop on the exchange of secret keys.  Source: photonics.com.   Optical Power Limiter Pushes Attack-Proof Quantum Communication Forward…

QuiX’ photonic processor is published! | In a scientific paper published in Materials for Quantum Technology today, QuiX Quantum demonstrates the world’s largest universal quantum photonic processor, which shows excellent performance for quantum information processing and computing applications. With this work, QuiX Quantum demonstrates the first commercially available, turn-key processor for photonic quantum computing.  Source: QuiX.   QuiX’ photonic processor is published!

Quest to Reveal Fundamental Secrets of the Universe Driven by Curiosity and Technology | Imagine the first of our species to lie beneath the glow of an evening sky. An enormous sense of awe, perhaps a little fear, fills them as they wonder at those seemingly infinite points of light and what they might mean. As humans, we evolved the capacity to ask big insightful questions about the world around us and worlds beyond us. We dare, even, to question our own origins.  Source: SciTechDaily.   Quest to Reveal Fundamental Secrets of the Universe Driven by Curiosity and Technology…

Mitigating Threats to Encryption From Quantum and Bad Random | The latest developments in integrated photonics and their applications will be discussed at the virtual 2021 OSA Advanced Photonics Congress 26 – 30 July. The event, comprised of five topical meetings, will feature presentations on photonic device research and development and their use in networks, and cross-cutting topics such as quantum science, free space communications, artificial intelligence (AI) and machine learning. Technical sessions will be presented live from the Eastern Daylight Time Zone (EDT).  Source: EurekAlert.   Mitigating Threats to Encryption From Quantum and Bad Random…

Heavy fermions with graphene useful for quantum technology | Two researchers have combined their knowledge of strongly correlated physics, with a focus on heavy fermions, and 2D van der Waals materials to propose a novel way of advancing radiation-free quantum technology using subtly modified graphene. Aline Ramires from the Paul Scherrer Institute in Switzerland and Jose Lado from Aalto University in Finland have shown a new pathway to engineer the fundamental phenomena of rare-earth compounds, known as heavy fermion superconductors, using just graphene.  Source: materialstoday.   Heavy fermions with graphene useful for quantum technology…

Honeywell, Google bring practical quantum computers a big step closer | Honeywell and Google have detailed dueling demonstrations of logical qubits, a technology that can correct errors in potentially powerful but notoriously finicky quantum computers.  Source: cnet.   Honeywell, Google bring practical quantum computers a big step closer…

Watch how quantum computing technology can target space debris cleanup | The Digital Annealer system is being engineered in collaboration with Astroscale, the University of Glasgow and Amazon Web Services to improve mission planning so that a single spacecraft can efficiently select which pieces of space debris to remove in one mission, and at a faster rate than is currently possible. Using a digital circuit design inspired by quantum phenomena, the Digital Annealer focuses on rapidly solving complex combinatorial optimization problems — up to 10,000 times faster than conventional computing — without the added complications and costs typically associated with quantum computing methods.  Source: Engineering 360.   Watch how quantum computing technology can target space debris cleanup…
