However, due to the aforementioned division-by-zero problem, one needs to keep finite self-capacitances for Josephson junction elements within the construction of the Lagrangian, which can only be set to zero at the very end on the Hamiltonian level. Therefore, one has to carry around a ...
Appendix B of SM discusses an alternative approach to the construction of Up(α), in which the ansatz is modified during the optimization process Full size image For a given ansatz, such as the one in Fig. 2, parameter optimization involves evaluating the cost C on a quantum computer for ...
These games were first considered in [31] as a natural generalization of classical XOR games, which have a great relevance in both quantum information and computer science. As we will see below, the relevant information of the game is encoded in the operator(4.1) which is a selfadjoint ...
In subject area: Computer Science A Quantum Algorithm refers to the use of quantum mechanical principles to carry out computational tasks or calculations. It includes algorithms such as Shor's algorithm, Grover's algorithm, Deutsch-Jozsa algorithm, Simon's algorithm, and Bernstein-Vazirani algorithm,...
Draper Written: September 1, 1998 Abstract A new method for computing sums on a quantum computer is introduced. This technique uses the quantum Fourier transform and reduces the number of qubits necessary for addition by removing the need for temporary carry bits. This approach also allows the ...
The computing system can be programmed with computer-executable instructions to deposit the layers as described in Table 1. In one embodiment, a VCSEL can include: a GaAs substrate; a first mirror region located on the GaAs substrate and having a plurality of first mirror layers having one or...

In 1985 David Deutsch of the University of Oxford described the construction of quantum logic gates for a universal quantum computer, and in 1994 Peter Shor of AT&T devised an algorithm to factor numbers with a quantum computer that would require as few as six qubits (although many more qubits...
In the current era of noisy intermediate-scale quantum computers, noisy qubits can result in biased results for early quantum algorithm applications. This is a significant challenge for interpreting results from quantum computer simulations for quantum c
For larger lattice sizes N, the construction of the singlet states becomes more involved and will not be addressed here. Table 1 All basis states with baryon number B = 1 for a lattice with N = 4 spatial sites. Full size table Once we have constructed a basis for the B =...
