One-spin quantum logic gates from exchange interactions and a global magnetic field
Lian-Ao Wu, Daniel A. Lidar, Mark Friesen
It has been widely assumed that one-qubit gates in spin-based quantum computers suffer from severe technical difficulties. We show that one-qubit gates can in fact be generated usi…
Exponentially Localized Magnetic Fields for Single-Spin Quantum Logic Gates
Daniel A. Lidar, Joseph H. Thywissen
An infinite array of parallel current-carrying wires is known, from the field of neutral particle optics, to produce an exponentially localized magnetic field when the current dire…
On the Quantum Computational Complexity of the Ising Spin Glass Partition Function and of Knot Invariants
Daniel A. Lidar
It is shown that the canonical problem of classical statistical thermodynamics, the computation of the partition function, is in the case of +/-J Ising spin glasses a particular in…
Comment on "Quantum waveguide array generator for performing Fourier transforms: Alternate route to quantum computing"
Daniel A. Lidar
A Comment on the paper "Quantum waveguide array generator for performing Fourier transforms: Alternate route to quantum computing" by R. Akis and D.K. Ferry, Appl. Phys. Lett. 79,…
Comment on "Conservative Quantum Computing"
Daniel A. Lidar
A Comment on the paper "Conservative Quantum Computing" by M. Ozawa, Phys. Rev. Lett. 89, 057902 (2002). The author replies in Phys. Rev. Lett. 91, 089802 (2003).
Quantum tensor product structures are observable-induced
Paolo Zanardi, Daniel Lidar, Seth Lloyd
It is argued that the partition of a quantum system into subsystems is dictated by the set of operationally accessible interactions and measurements. The emergence of a multi-parti…
