The Quantum-Mechanical Model of an Atom02:45

The Quantum-Mechanical Model of an Atom

47.1K
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...

The Uncertainty Principle

25.5K
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 Role of Ion Channels in Neuronal Computation

3.2K
A postsynaptic neuron usually receives numerous impulses from several other presynaptic neurons. The axon hillock of the postsynaptic neuron integrates all these signals and determines the likelihood of firing an action potential.
Sometimes a single EPSP is strong enough to induce an action potential in the postsynaptic neuron. However, multiple presynaptic inputs must often create EPSPs around the same time for the postsynaptic neuron to be sufficiently depolarized to fire an action potential....

It is said that the energy of an electron in an atom is quantized; that is, it can be equal only to certain specific values and can jump from one energy level to another but not transition smoothly or stay between these levels.

Convolution Properties I

Convolution computations can be simplified by utilizing their inherent properties.
The commutative property reveals that the input and the impulse response of an LTI (Linear Time-Invariant) system can be interchanged without affecting the output:

Entropy Change in Reversible Processes01:10

Entropy Change in Reversible Processes

2.4K
In the Carnot engine, which achieves the maximum efficiency between two reservoirs of fixed temperatures, the total change in entropy is zero. The observation can be generalized by considering any reversible cyclic process consisting of many Carnot cycles. Thus, it can be stated that the total entropy change of any ideal reversible cycle is zero.
The statement can be further generalized to prove that entropy is a state function. Take a cyclic process between any two points on a p-V diagram.

Area of Science:

  • Quantum Information Science
  • Foundations of Quantum Mechanics

Background:

  • Quantum computing offers significant advantages over classical computing, yet the origin of this power remains unclear.
  • Contextuality, a uniquely quantum phenomenon that defies classical 'hidden variable' explanations, is a key characteristic of quantum mechanics.

Purpose of the Study:

  • To establish a fundamental equivalence between the emergence of contextuality and the potential for universal quantum computation.
  • To unify the understanding of quantum information resources, linking contextuality, non-locality, and quantum advantage.

Main Methods:

  • Proving a theoretical equivalence between contextuality and universal quantum computation through 'magic state' distillation.
  • Analyzing contextuality as a unifying framework for quantum information resources, including non-locality.

Main Results:

  • Demonstrated that contextuality is a necessary and sufficient condition for universal quantum computation via magic state distillation.
  • Established non-locality as a specific form of contextuality, highlighting its role in quantum communication advantages.
  • Advanced the resource framework for quantum computation, offering practical applications.

Conclusions:

  • Contextuality is identified as the fundamental resource enabling universal quantum computation.
  • This work provides a unified view of quantum information resources and their role in quantum advantage.
  • The findings have implications for characterizing quantum computation schemes and bounding classical simulation costs.
