QUANTUM SPIN GLASSES IN FINITE DIMENSIONS
... spin glass problem and the value of Γ tunes the strength of the quantum fluctuations. At zero temperature and Γ = 0 the system described by (1) will be in its uniquely determined ground state, which is identical to the classical ground state of the EAspin glass model. In this case one has hσiz i = ± ...

Triple to quintuple quantum dots for making multiple qubits
... To date various types of spin qubits have been developed with quantum dots including spin-1/2, singlet-triplet and exchange-only qubits. We have used a micro-magnet technique to make two spin-1/2 qubits and an entangling gate with a double quantum dot. The necessary step for further scaling up the q ...

A Quantum Structure Description of the Liar Paradox
... We recall some elementary properties of a spin state. Elementary particles - like the electron - are bestowed with a property referred to as an intrinsic angular momentum or spin. The spin of a particle is quantised: upon measurement the particle only exposes a finite number of distinct spin values. ...

... Given a family of symplectictomorphic spaces such as Yb , one can often produce a ‘symplectic connection’ which associates to a path in the base a symplectomorphism between the fibers. Up to a hamiltonian isotopy, this symplectomorphism depends only on the homotopy class of the path. Since two objec ...
