... Figure 1a shows a SEM image of the persistent current qubit (inner loop) and the measuring dc SQUID (outer) loop. A schematic of the qubit and the measuring circuit is shown in Figure 1b, where the Josephson junctions are denoted by x's. The sample is fabricated at MIT Lincoln Laboratory in niobium ...

Introduction to Quantum Computation THE JOY OF ENTANGLEMENT
... (Here, as in the previous section, | ↑i and | ↓i represent spin parallel and antiparallel, respectively, to the z-axis.) We assume (implicitly, since spatial wave functions don’t appear in Eq. 9) that each particle is in a localized state remote from the other particles. We prepare an ensemble of pa ...

... The qubits levels can be formed by either the energy levels of an electron in a potential well (such as a quantum dot or an impurity ion) or by the spin states of the electron (or the nucleus). The former are examples of charge qubits. The charge qubits have high energy splitting, and can be manipul ...

How to Construct Quantum Random Functions

The security proof consists of two hybrid arguments: the first across levels of the tree, and the second across the nodes in a particular level. The first step has only polynomially many hybrids since the tree’s depth is a polynomial. For the se ...
