Hagelstein and Chaudhary have recently criticized our low energy nuclear reaction rates in chemical cells based on our computed electron mass renormalization for surface electrons of metal hydride electrodes. They further criticize our electron mass renormalization in exploding wire systems which is very strange because mass renormalization was {em never even mentioned} in our exploding wire work. Here we show that the calculations of Hagelstein and Chaudhary are erroneous in that they are in conflict with the Gauss law, i.e. they have arbitrarily removed all Coulomb interactions in electromagnetic propagators. They have also ignored substantial Ampere interactions in favor of computing only totally negligible contributions. When the fallacious considerations of Hagelstein and Chaudhary are clearly exposed, it becomes evident that our previous calculations remain valid.
Quantum annealing has the potential to provide a speedup over classical algorithms in solving optimization problems. Just as for any other quantum device, suppressing Hamiltonian control errors will be necessary before quantum annealers can achieve s
This work aims at giving Trotter errors in digital quantum simulation (DQS) of collective spin systems an interpretation in terms of quantum chaos of the kicked top. In particular, for DQS of such systems, regular dynamics of the kicked top ensures c
Robust, high-fidelity readout is central to quantum device performance. Overcoming poor readout is an increasingly urgent challenge for devices based on solid-state spin defects, particularly given their rapid adoption in quantum sensing, quantum inf
Crosstalk occurs in most quantum computing systems with more than one qubit. It can cause a variety of correlated and nonlocal crosstalk errors that can be especially harmful to fault-tolerant quantum error correction, which generally relies on error
We show how entanglement shared between encoder and decoder can simplify the theory of quantum error correction. The entanglement-assisted quantum codes we describe do not require the dual-containing constraint necessary for standard quantum error co
