PERSPECTIVES so that only a single channel is conducting 12 13 the researchers can detect small changes in the electrostatic environment Hence when an antiparallel spin qubit pair tunnels into the right dot the quantum wire can detect its presence there The remarkable recent experimental realizations involving the control manipulation and detection of spins in quantum dots 14 18 are breathtaking they definitely pave the way to an actual implementation of the spin parity meter of Loss and Engel A successful realization of spinbased quantum computing depends on a detailed experimental investigation of the decoherence of the spin qubits that is the loss of their quantum mechanical integrity due to interactions with the environment With a spin parity meter in hand together with spin qubit rotations perhaps via pulsed magnetic fields and with decoherence under control spin based quantum computation may be closer at hand References and Notes 1 H A Engel D Loss Science 309 586 2005 2 C W J Beenakker et al Phys Rev Lett 93 020501 2004 3 M A Nielsen I L Chuang Quantum Computation and Quantum Information Cambridge Univ Press New York 2000 4 E Knill et al Nature 409 46 2001 5 D Loss D P DiVincenzo Phys Rev A 57 120 1998 6 D D Awschalom D Loss N Samarth Eds Semiconductor Spintronics and Quantum Computation Springer Berlin 2002 7 J M Kikkawa D D Awschalom Nature 397 139 1999 8 R Fiederling et al Nature 402 787 1999 9 Y Ohno et al Nature 402 790 1999 10 For quantum spin filtering with spin dependent magnetic barriers see J C Egues Phys Rev Lett 80 4578 1998 11 B M Terhal D P DiVincenzo Phys Rev A 65 032325 2002 12 M Field et al Phys Rev Lett 70 1311 1993 13 J M Elzerman et al Phys Rev B 67 R161308 2003 14 J A Folk R M Potok C M Marcus V Umansky Science 299 679 2003 15 T Hayashi et al Phys Rev Lett 91 226804 2003 16 J M Elzerman et al Nature 430 431 2004 17 M Kroutvar et al Nature 432 81 2004 18 For a review of spin based quantum computing and a detailed account of recent
