Spins in few-electron quantum dots
The canonical example of a quantum-mechanical two-level system is spin. The simplest picture of spin is a magnetic moment pointing up or down. The full quantum properties of spin become apparent in
NMR techniques for quantum control and computation
Fifty years of developments in nuclear magnetic resonance (NMR) have resulted in an unrivaled degree of control of the dynamics of coupled two-level quantum systems. This coherent control of nuclear
Experimental realization of Shor's quantum factoring algorithm using nuclear magnetic resonance
TLDR
A simple, parameter-free but predictive model of decoherence effects in the authors' system is presented, which is in principle scalable to systems containing many quantum bits, but such scalability is not implied by the present work.
Driven coherent oscillations of a single electron spin in a quantum dot
TLDR
The experimental realization of single electron spin rotations in a double quantum dot is reported, demonstrating the feasibility of operating single-electron spins in a quantum dot as quantum bits.
Science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems.
TLDR
An overview of the key aspects of graphene and related materials, ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries are provided.
Single-shot read-out of an individual electron spin in a quantum dot
TLDR
Electrical single-shot measurement of the state of an individual electron spin in a semiconductor quantum dot is demonstrated using spin-to-charge conversion of a single electron confined in the dot, and the single-electron charge is detected using a quantum point contact.
Gate-induced insulating state in bilayer graphene devices.
TLDR
This work demonstrates the controlled induction of an insulating state--with large suppression of the conductivity--in bilayer graphene, by using a double-gate device configuration that enables an electric field to be applied perpendicular to the plane.
Coherent Control of a Single Electron Spin with Electric Fields
TLDR
The experimentally realized coherent control of a single-electron spin in a quantum dot using an oscillating electric field generated by a local gate to establish the feasibility of fully electrical manipulation of spin qubits.
Bipolar supercurrent in graphene
TLDR
Light is shed on the special role of time reversal symmetry in graphene, and phase coherent electronic transport at the Dirac point is demonstrated, finding that not only the normal state conductance of graphene is finite, but also a finite supercurrent can flow at zero charge density.
DNA translocation through graphene nanopores.
TLDR
This paper provides proof of concept that it is possible to realize and use ultrathin nanopores fabricated in graphene monolayers for single-molecule DNA translocation.
