Solid State NMR
Anatoly developed more efficient sequences for heteronuclear broadband decoupling, such as SPINAL, CPM m–n, and nPPM.
His deep insights into nuclear dipole-dipole interactions brought methods like ‘adiabatic cross-polarization’ and ‘uniform saturation’ into the world.
NMR Molecular Photography
Anatoly’s demonstrated that one can encode bits of information on a single molecule. The figure shows a pixelated image, which was encoded in the nuclear spins of the molecule.
Long-lived NMR echoes in solids
The same technique used for the molecular photography enabled to obtain high-resolution MRI images of objects with dipolar-broadened spectra, such as a liquid crystal and a pencil eraser.
“Schrödinger cat” states and quantum amplifier
Anatoly had his unconventional approach to NMR quantum information processing. He demonstrated the so-called pseudo-pure ground and maximally entangled states on the largest and most complex systems at the moment. The figure shows the evidences of such states on a 7-qubit system.
He devised schemes of amplified detection and measurement with a help of the maximally entangled states. The figure shows his idea of expanding the state of a single qubit into the state of N quits.
He designed a quantum amplifier based on a 1D Ising chain. Here, one does not need any prepared entangled states.
Broad-band Suppression of Radiation Damping
Anatoly had an idea for broad-band suppression of radiation damping. With this simple technique, one can obtain spectra free from radiation damping of samples such as Vodka and gasoline.
Controlling spontaneous emission by a sequence of phase kicks
Anatoly proposed models to study the measurement and decoherence processes in quantum systems. One model was an atom in a box interacting a photon.
