Magnetic qubits as hardware for quantum computers
J. Tejada, E. M. Chudnovsky, E. del Barco +2
We propose two potential realisations for quantum bits based on nanometre scale magnetic particles of large spin S and high anisotropy molecular clusters. In case (1) the bit-value…
Coherent Tunneling in Fe-8 Molecular Nanomagnets: Response to the Comment by Bellessa (arXiv:cond-mat/0006441)
E. del Barco, J. M. Hernandez, J. Tejada +2
Response to the Comment by Bellessa (arXiv:cond-mat/0006441).
Ferromagnetic Film on a Superconducting Substrate
L. N. Bulaevskii, E. M. Chudnovsky
We study the equilibrium domain structure and magnetic flux around a ferromagnetic (FM) film with perpendicular magnetization M_0 on a superconducting (SC) substrate. At 4πM_0<H_{c…
Quantum Coherence and Decoherence in Magnetic Nanostructures
Eugene M. Chudnovsky
The prospect of developing magnetic qubits is discussed. The first part of the article makes suggestions on how to achieve the coherent quantum superposition of spin states in smal…
Quantum statistical metastability for a finite spin
D. A. Garanin, E. M. Chudnovsky
We study quantum-classical escape-rate transitions for uniaxial and biaxial models with finite spins S=10 (such as Mn_12Ac and Fe_8) and S=100 by a direct numerical approach. At se…
Spin Tunneling in Mn-12 Cannot be Assisted by Phonons at Millikelvin Temperatures [Comment on PRL 83, 416 (1999) by Bellessa et al]
E. M. Chudnovsky, D. A. Garanin
Recently, Bellessa et al in a Physical Review Letter entitled "Phonon-Assisted Tunneling in High-Spin Molecules: Experimental Evidence", reported observation of a peak in the imagi…
