Abstract
The invention relates to an improved logic device providing fast logic implementation based on the magnetic resonance of a collection of interacting or non-interacting spins or spin systems. This fast logic device can form the centerpiece of a novel spin computer or hybrid spin computer. In one implementation, the logic device includes a spin system with a sufficiently long relaxation time in a magnetic field which provides a bi-stable state. A probehead, console and receiver enable the system to access the bi-stable state using magnetic resonance excitation and detection, and field gradients permit addressing of distinct memory cells in the spin system.
Claims7
An improved logic device which comprises, a resonant radio frequency (RF) source having a continuous wave (CW) RF output, the CW RF output being fed to a modulator/driver connected to a pulser providing a DC gating pulse, the resultant RF pulse being connected to the input of a power amplifier, the power amplifier output being connected to a probehead housing a spin system in the center of a magnetic field, the probehead output being connected to a preamplifier/receiver, which also get a reference input from the RF source, the output of said preamplifier/receiver being connected through an analog to digital convertor (ADC) to a computer device capable of providing timing and performance control, another input to said probehead being connected to a gradient control unit capable of providing orthogonal gradient pulses for addressing memory elements in said spin system.
