Spins in solids or in molecules possess discrete energy levels, and the associated quantum
states can be tuned and coherently manipulated by means of external electromagnetic …

This review describes recent groundbreaking results in Si, Si/SiGe, and dopant-based
quantum dots, and it highlights the remarkable advances in Si-based quantum physics that …

A single atom is the prototypical quantum system, and a natural candidate for a quantum bit,
or qubit—the elementary unit of a quantum computer. Atoms have been successfully used to …

Organic semiconductors are studied intensively for applications in electronics and optics,
and even spin-based information technology, or spintronics. Fundamental quantities in …

The term 'molecular magnet'generally refers to a molecular entity containing several
magnetic ions whose coupled spins generate a collective spin, S (ref.). Such complex multi …

We report a demonstration of two-dimensional (2D) terahertz (THz) magnetic resonance
spectroscopy using the magnetic fields of two time-delayed THz pulses. We apply the …

This introductory review discusses the main problems facing the attempt to build quantum
information processing systems (like quantum computers) from spin-based qubits. We …

Silicon is promising for spin-based quantum computation because nuclear spins, a source of
magnetic noise, may be eliminated through isotopic enrichment. Long spin decoherence …

An anisotropic high-spin qubit with long coherence time could scale the quantum system up.
It has been proposed that Grover's algorithm can be implemented in such systems …

We review the progress made in integrating magnetic molecules containing transition metal
ions into nanoelectronic solid-state devices and using them as molecular spin qubits …
