The de Broglie Wavelength

The de Broglie Wavelength

In the macroscopic world, objects that are large enough to be seen by the naked eye follow the rules of classical physics. A billiard ball moving on a table will behave like a particle; it will continue traveling in a straight line unless it collides with another ball, or it is acted on by some other force, such as friction. The ball has a well-defined position and velocity or well-defined momentum, p = mv, which is defined by mass m and velocity v at any given moment. This is the typical...

The Uncertainty Principle

The Uncertainty Principle

Werner Heisenberg considered the limits of how accurately one can measure properties of an electron or other microscopic particles. He determined that there is a fundamental limit to how accurately one can measure both a particle’s position and its momentum simultaneously. The more accurate the measurement of the momentum of a particle is known, the less accurate the position at that time is known and vice versa. This is what is now called the Heisenberg uncertainty principle. He...

The Quantum-Mechanical Model of an Atom

The Quantum-Mechanical Model of an Atom

Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, Erwin Schrödinger extended de Broglie’s work by deriving what is now known as the Schrödinger equation. When Schrödinger applied his equation to hydrogen-like atoms, he was able to reproduce Bohr’s expression for the energy and, thus, the Rydberg formula governing hydrogen spectra.

Background:

Characterizing multiparticle quantum states is crucial for quantum information processing.
Standard quantum state tomography requires a high measurement complexity, scaling exponentially with the number of particles.

Main Methods:

Utilizing quantum teleportation to transfer a density matrix element from a virtual logical qubit to a single physical qubit.
Non-destructive readout of the teleported density matrix element on the physical qubit.
Experimental implementation using a photonic mixed quantum state beyond a single photon.

Main Results:

Successfully demonstrated the direct measurement of a photonic mixed quantum state's wave function.
Achieved the first-ever direct measurement of a multiparticle wave function using a single observable.
