Gallagher-Moszkowski (GM) doublet bands inHo162

Abstract

High-spin states in 162 Ho have been populated in the reaction 160 Gd( 7 Li, 5n) at a beam energy of 49 MeV. The K π = 1 − band, the low-K Gallagher-Moszkowski (GM) partner band of known high-K(K π = 6 − ) band, based on the configuration π 7/2 − [523] ⊗ ν5/2 + [642], and the K π = 6 + band, the high-K GM partner band of known low-K(K π = 1 + ) band, based on the configuration π 7/2 − [523] ⊗ ν5/2 − [523], have been identified. GM splitting energies, defined as E GM = E K int − E K int , 80 keV and −135 keV were extracted from these two sets of GM doublet bands, respectively. They are comparable with 65 keV and −145 keV, reported recently by Hojman et al. for the corresponding configurations π 7/2 − [523] ⊗ ν5/2 + [642] and π 7/2 − [523] ⊗ ν5/2 − [523] in 164 Ho, respectively.

Transfer and teleportation of quantum states encoded in decoherence-free subspace

“…So our scheme could not only protect quantum information from some decoherence, but also reduce the experimental difficulty compared to the previous schemes [1,4,5,11].

“…In addition, auxiliary entangled photon pairs, as employed in [5], are unnecessary in our two-logic-qubit conditional gate. Moreover, for quantum state transfer, neither the entangled photon pairs [11] nor the special time-symmetric wave packet of the photons [1] is necessary in our scheme. So our scheme could not only protect quantum information from some decoherence, but also reduce the experimental difficulty compared to the previous schemes [1,4,5,11].…”

“…Hk, 42.50.Dv Quantum state transfer and teleportation are significant components in quantum information processing, especially for quantum network. As the confined atoms in cavity QED system are well suited for storing qubits in long-lived internal states, spatially separated cavities could be used to build a quantum network assisted by photons [1,2,3,4,5,6,7,11]. On the other hand, decoherence due to the inevitable interaction with environment destroys quantum coherence.…”
