Two different approaches to describe the transport properties of single molecules:
1.To study steady-state transport, a combination of density functional theory (DFT) with Greens function techniques has been developed and widely used by several groups and can now be considered the standard ab-initio technique to calculate the current-voltage (IV) characteristics of single molecules sandwiched between two "semi-infinite" metallic leads.
2.The second approach pursued in our group focuses on time-dependent phenomena. The Landauer-plus-DFT approach, by construction, inherits the main assumption of the Landauer formalism that for a system driven out of equilibrium by a dc bias, a steady current will eventually be achieved. In other words, the dynamical formation of a steady state does not follow from the formalism but rather constitutes an assumption.

Quantum mechanics is a fundamental theory in physics which describes nature at the smallest scales of energy levels of atoms and subatomic particles. At the scale of atoms and electrons, many of the equations of classical mechanics, which describe how things move at everyday sizes and speeds, cease to be useful. In classical mechanics, objects exist in a specific place at a specific time. However, in quantum mechanics, objects instead exist in a haze of probability; they have a certain chance of being at point A, another chance of being at point B and so on.

Quantum optics (QO) is a field of research that uses semi-classical and quantum-mechanical physics to investigate phenomena involving light and its interactions with matter at submicroscopic levels. In other words it is quantum mechanics applied to photons or light.
Light propagating in a vacuum has its energy and momentum quantized according to an integer number of particles known as photons. Quantum optics studies the nature and effects of light as quantized photons. The first major development leading to that understanding was the correct modeling of the blackbody radiation spectrum by Max Planck, under the hypothesis of light being emitted in discrete units of energy. The photoelectric effect was further evidence of this quantization as explained by Einstein ,Niels Bohr showed that the hypothesis of optical radiation being quantized corresponded to his theory of the quantized energy levels of atoms, and the spectrum of discharge emission from hydrogen in particular. The understanding of the interaction between light and matter following these developments was crucial for the development of quantum mechanics as a whole. However, the subfields of quantum mechanics dealing with matter-light interaction were principally regarded as research into matter rather than into light; hence one rather spoke of atom physics and quantum electronics.

Quantum chromodynamics (QCD) is the theory of the strong interaction between quarks and gluons, the fundamental particles that make up composite hadrons such as the proton, neutron and pion. QCD is a type of quantum field theory called a non-abelian gauge theory, with symmetry group SU(3). The QCD analog of electric charge is a property called color. Gluons are the force carrier of the theory, like photons are for the electromagnetic force in quantum electrodynamics. The theory is an important part of the Standard Model of particle physics.
QCD exhibits two main properties:
- Color confinement-This is a consequence of the constant force between two color charges as they are separated: In order to increase the separation between two quarks within a hadron, ever-increasing amounts of energy are required. Eventually this energy produces a quark–antiquark pair, turning the initial hadron into a pair of hadrons instead of producing an isolated color charge. Although analytically unproven, color confinement is well established from lattice QCD calculations and decades of experiments.
- Asymptotic freedom- A steady reduction in the strength of interactions between quarks and gluons as the energy scale of those interactions increases (and the corresponding length scale decreases).

Quantum condensed matter theory attempts to describe and sometimes to predict the behavior of systems of relatively large numbers of particles (as many as 1024 for bulk systems or as few as 1010 for two-dimensional layers or even fewer for carbon nanotubes) at low energies, typically far less than 0.1 eV. The variety of systems that are treated is extremely rich, including metals and superconductors, ionic and magnetic systems, semiconductors, glasses and superfluid. The basic tools of the condensed matter theorist are quantum mechanics and statistical mechanics as well as many-body theory, path integrals, topology, group theory, density functional theory, computational physics and so forth.

The quantum field theory is an area of theoretical physics, in the principles of classic field theory and the quantum mechanics are combined to form an expanded theory. It goes beyond quantum mechanics by uniformly describing particles and fields. Not only so-called observables are quantized, but also the interacting ones fields themselves; Fields and observables are treated analogously.The quantization of the fields is also called second quantization.This explicitly takes into account the formation and annihilation of elementary particles.
The methods of quantum field theory are mainly used in elementary particle physics and in statistical mechanics. A distinction is made here between relativistic quantum field theories, which take into account the special theory of relativity and are frequently used in elementary particle physics, and non-relativistic quantum field theories, which are relevant for example in solid state physics.

String theory is a framework to build models of quantum gravity.This relates quantum gravity in a spacetime that asymptotes to anti-de Sitter space with an ordinary quantum field theory that lives in one lower dimension, and has a symmetry under angle-preserving (conformal) transformations.
This is interesting because it provides us with a non-perturbative definition of quantum gravity, in a setup that is rich enough to permit black holes, non-trivial scattering, and is related to cosmological models.

Quantum cryptography is the science of exploiting quantum mechanical properties to perform cryptographic tasks. The best known example of quantum cryptography is quantum key distribution which offers an information-theoretically secure solution to the key exchange problem. The advantage of quantum cryptography lies in the fact that it allows the completion of various cryptographic tasks that are proven or conjectured to be impossible using only classical (i.e. non-quantum) communication. For example, it is impossible to copy data encoded in a quantum state. If one attempts to read the encoded data, the quantum state will be changed (No-Cloning Theorem). This could be used to detect eavesdropping in quantum key distribution.
Schrödinger equation is a mathematical equation that describes the changes over time of a physical system in which quantum effects, such as wave–particle duality, are significant. These systems are referred to as quantum (mechanical) systems. The equation is considered a central result in the study of quantum systems, and its derivation was a significant landmark in the development of the theory of quantum mechanics. It was named after Erwin Schrödinger,

Quantum information science is an area of study based on the idea that information science depends on quantum effects in physics. It includes theoretical issues in computational models as well as more experimental topics in quantum physics including what can and cannot be done with quantum information. The term quantum information theory is sometimes used, but it fails to encompass experimental research in the area and can be confused with a subfield of quantum information science that studies the processing of quantum information.
