Carbon nanotubes are a versatile material in which many aspects of condensed matter physics come together. Recent discoveries have uncovered new phenomena that completely change our understanding of transport in these devices, especially the role of the spin and valley degrees of freedom. This review describes the modern understanding of transport through nanotube devices. Unlike in conventional semiconductors, electrons in nanotubes have two angular momentum quantum numbers, arising from spin… 
Microwave spectroscopy of a carbon nanotube charge qubit
Carbon nanotube quantum dots allow accurate control of electron charge, spin and valley degrees of freedom in a material which is atomically perfect and can be grown isotopically pure. These
Highly coherent spin states in carbon nanotubes coupled to cavity photons
Spins confined in quantum dots are considered as a promising platform for quantum information processing. While many advanced quantum operations have been demonstrated, experimental as well as
Hole spins in GE-SI nanowires
In a universal quantum computer, coherent control over the state of a quantum mechanical two-level system is needed. This requires interactions of the quantum state with its environment. Inherently,
Spin-valley dynamics of electrically driven ambipolar carbon-nanotube quantum dots.
It is found that the transitions lifting the Pauli blockade are strongly influenced by coupling to a vacuum state with an empty n dot and a fully filled p dot, and appears effective for surprisingly large energy splitting between the (1e,1h) ground state and the vacuum (0e, 0h) state.
Blocking transport resonances via Kondo many-body entanglement in quantum dots
This work finds that only resonances involving flips of the Kramers pseudospins, associated to this symmetry, are observed at temperatures and voltages below the corresponding Kondo scale, and demonstrates the robust formation of entangled many-body states with no net pseudospin.
Quantum Noise in Carbon Nanotubes as a Probe of Correlations in the Kondo Regime
Most of the time, electronic excitations in mesoscopic conductors are well described, around equilibrium, by non-interacting Landau quasi-particles. This allows a good understanding of the transport

It is demonstrated that the fractional resonances-counterparts of multiphoton transitions for atoms in strong laser fields-occurring in electrically controlled nanodevices already at moderate ac amplitudes-can be used to maintain the spin-flip transitions.
Interaction-Driven Giant Orbital Magnetic Moments in Carbon Nanotubes.
This work addresses the outstanding anomaly of exceptionally large orbital magnetic moments in carbon nanotube quantum dots and carries out quasiparticle calculations, and finds the giant magnetic moments can only be captured by considering a self-energy correction to the electronic band structure due to electron-electron interactions.
Quantum nuclear motion of helium and molecular nitrogen clusters in carbon nanotubes
We study the quantum nuclear motion of N 4He atoms or N N2 molecules (N < 4) confined in carbon nanotubes using an ad hoc-developed nuclear wave function-based approach. Density functional theory

In this overview paper, we present low-temperature electronic transport measurements of carbon nanotube quantum dots with a back gate. In a semiconducting tube, charge carriers could be completely

It is reported that electrically contacted single-walled carbon nanotubes can serve as powerful probes of Kondo physics, demonstrating the universality of the Kondo effect.

We present a theoretical study of the Pauli or spin-valley blockade for double quantum dots in semiconducting carbon nanotubes. In our model we take into account the following characteristic features
Orbital Kondo effect in carbon nanotubes
It is shown that the unique electronic structure of carbon nanotubes enables the observation of a purely orbital Kondo effect, and it is concluded that the orbital quantum number is conserved during tunnelling.

This work exploits the bandgap of low-disorder nanotubes to demonstrate robust Pauli blockade based on both valley and spin selection rules, and indicates the feasibility of valley-spin qubits in carbon nanot tubes.

Understanding the influence of vibrational motion of the atoms on electronic transitions in molecules constitutes a cornerstone of quantum physics, as epitomized by the Franck–Condon principle1, 2 of
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
Coupling of spin and orbital motion of electrons in carbon nanotubes
These measurements are consistent with recent theories that predict the existence of spin–orbit coupling in curved graphene and describe it as a spin-dependent topological phase in nanotubes and have important implications for spin-based applications in carbon-based systems.
A valley-spin qubit in a carbon nanotube.
A qubit encoded in two nanotube valley-spin states is realized, with coherent manipulation via electrically driven spin resonance mediated by a bend in the nanotubes, showing that, even with low nuclear spin abundance, coherence can be strongly degraded if the qubit states are coupled to electric fields.
