The Uncertainty Principle04:08

The Uncertainty Principle

25.4K
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...

Norton's Theorem01:14

Norton's Theorem

2.0K
Norton's theorem is a fundamental principle stating that a linear two-terminal circuit can be substituted with an equivalent circuit, which comprises a current source (ⅠN) in parallel with a resistor (RN). Here, ⅠN represents the short-circuit current flowing through the terminals, and RN stands for the input or equivalent resistance at the terminals when all independent sources are deactivated. This implies that the circuit illustrated in Figure (a) can be exchanged with the one...

Stability of Equilibrium Configuration01:23

Stability of Equilibrium Configuration

998
Understanding the stability of equilibrium configurations is a fundamental part of mechanical engineering. In any system, there are three distinct types of equilibrium: stable, neutral, and unstable.
A stable equilibrium occurs when a system tends to return to its original position when given a small displacement, and the potential energy is at its minimum. An example of a stable equilibrium is when a cantilever beam is fixed at one end and a weight is attached to the other end. If the weight...

The Quantum-Mechanical Model of an Atom

46.9K
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...

Propagation of Uncertainty from Random Error00:59

Propagation of Uncertainty from Random Error

1.9K
An experiment often consists of more than a single step. In this case, measurements at each step give rise to uncertainty. Because the measurements occur in successive steps, the uncertainty in one step necessarily contributes to that in the subsequent step. As we perform statistical analysis on these types of experiments, we must learn to account for the propagation of uncertainty from one step to the next. The propagation of uncertainty depends on the type of arithmetic operation performed on...

Quantum Numbers02:43

Quantum Numbers

39.7K
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.

Area of Science:

  • Quantum Information Science
  • Cryptography
  • Quantum Communication

Background:

  • Traditional commitment schemes often rely on pre-shared secrets or authenticated channels, posing security vulnerabilities.
  • Existing position-based cryptography has limitations in achieving unconditional security.
  • Non-local quantum correlations offer unique properties for secure communication protocols.

Purpose of the Study:

  • To present a novel, unconditionally secure commitment scheme leveraging position-verification and non-local quantum correlations.
  • To eliminate the need for pre-shared data or trusted quantum/classical channels between committer and receiver.
  • To ensure the scheme is secure against various attacks, including those from the committer, receiver, and third parties.

Main Methods:

  • Developed a commitment scheme that uses the committer's physical position as a credential for security.
  • Employed non-local quantum correlations to validate the commitment and verify the committer's position in a single round.
  • Designed the protocol to bound the committer's reveal time and prevent information leakage before commitment.

Main Results:

  • The proposed scheme achieves unconditional security based solely on the committer's position and quantum correlations.
  • It successfully commits both classical bits and quantum qubits.
  • The scheme is demonstrated to be secure against both the committer/receiver and external adversaries, specifically evading Mayers and Lo-Chau attacks.

Conclusions:

  • This work introduces a groundbreaking position-based quantum commitment scheme with enhanced security features.
  • The scheme removes reliance on traditional cryptographic assumptions, offering a new paradigm for secure commitment protocols.
  • It provides a robust and unconditionally secure solution for commitment tasks in quantum information science.
