Quantum kernel methods are usually believed to enjoy better trainability than quantum neural networks which may suffer from a well-studied barren plateau. Here, building over previous evidence, the authors show
Building Quantum Computers: A Practical Introduction by Shayan Majidy, Christopher Wilson, and Raymond Laflamme has been published by Cambridge University Press and will be released in the US on September 30. The authors invited me to write a Foreword for the book, which I was happy to do. T...

Specifically, it will be promising for practical applications, such as designing lower-dimensional higher-Q-factor topological cavities if the corner states in higher-order topological BICs can be experimentally independently triggered53. Here, we present the experimental observation of the higher-order ...
In particular, the resonance width can be enforced to be equal to zero, which leads to an electron localization with the Fermi energy embedded in the propagation band of the wire, i.e., the bound state in the continuum (BSC). We show that, for positive values of the potential, a ...
8, panels (a), (d) and (f) at φπ do not show a significant difference between them—the common characteristic is that the hybridization between Majoranas bound states in the nanowires is zero (ξM, (1/2) 0). Panels (b), (c) and (e) all of them have the presence of a ...
The deterministic EPPs [16–20] are far different from the conventional EPPs [13–15] as they work in a completely deterministic way, not in a probabilistic way, and they can reduce the quantum resource sacrificed largely, which make them very useful in practical quantum repeaters. In 2011, ...
leading to significant computational efficiency improvements. This approach not only advances our understanding of quantum systems but also serves as a precursor for practical applications, such as the adiabatic preparation of tensor ne...
Still, the autonomous quantum refrigerator wasn’t practical. Keeping the ion cold and maintaining its quantum behavior required substantial work. My community needed, I wrote in my epilogue, an analogue of solar panels in southern California. (I probably drafted the epilogue during a Boston winter...
However, this result does not exclude the possibility of practical schemes in the bounded- or noisy-quantum-storage model (see above). Later Beigi and König improved the amount of EPR pairs needed in the general attack against position-verification protocols to exponential. They also showed ...
