If Quantum Computing Is Solving âImpossibleâ Questions, How Do We Know Theyâre Right?
(scitechdaily.com)
A new Swinburne study is addressing a core paradox: if quantum computing is solving problems that cannot be checked by conventional methods, how can we be certain the results are correct? Quantum computing has the potential to tackle problems once thought unsolvable in areas including physics, medic...
Princeton engineers extended qubit lifetimes using a new tantalum-silicon design that sharply cuts energy loss. The improvement could enable large, stable quantum processors capable of real-world problem solving. Princeton engineers have taken a significant step toward developing useful quantum comp...
Quantum Computing Breakthrough Shrinks Key Device to 100x Smaller Than a Human Hair
(scitechdaily.com)
A new chip-scale device offers unprecedented control over laser frequencies, a key ingredient for large-scale quantum computing. Researchers have achieved an important step forward in quantum computing by developing a device so small that it is almost 100 times thinner than a human hair. The advance...
Replication is a cornerstone of science, yet even in the natural sciences, attempts to reproduce results do not always succeed. Quantum computing promises machines that can solve certain problems far beyond todayâs computers, but it faces a stubborn obstacle: quantum information is extremely fragile...
By adjusting a simple chemical ratio, scientists discovered a new way to control exotic quantum states that could underpin the next generation of quantum computers. Even supercomputers can stall out on problems where nature refuses to play by everyday rules. Predicting how complex molecules behave o...
By combining surface codes with lattice surgery, researchers have shown how logical qubits can be manipulated and entangled while remaining protected from errors. Quantum computers are often described as a glimpse of a faster, more powerful future. The catch is that todayâs devices are fragile in a ...
Quantum Computing Breakthrough: Scientists Finally Unlock the Secret of Majorana Qubits
(scitechdaily.com)
Scientists have finally figured out how to read ultra-secure Majorana qubitsâbringing robust quantum computing a big step closer. âThis is a crucial advance,â says RamĂłn Aguado, a CSIC researcher at the Madrid Institute of Materials Science (ICMM) and co author of the study. He explains that the tea...
NbRe may be a long-sought triplet superconductor, offering zero-resistance spin transport and major advances in quantum computing. Physicists have searched for decades for materials known as triplet superconductors because of their potential to enable extremely energy-efficient technologies. These m...

"This course tries to connect quantum computing to the wider intellectual world. We'll start out with various scientific, mathematical, or philosophical problems that predate quantum computing: for example, the measurement problem, P versus NP, the existence of secure cryptography, the Humean proble...
Paper is [here](https://arxiv.org/abs/1804.01082). Abstract:
"We present the first protocol allowing a classical computer to interactively verify the result of an efficient quantum computation. We achieve this by constructing a measurement protocol, which enables a classical verifier to use a qua...
