Extraction: Partition and Distribution Coefficients

4.3K
The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.
For extracting a solute from an aqueous phase into an...

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...

Distribution Reliability and Automation

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...

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.

Free Energy Changes for Nonstandard States

10.7K
The free energy change for a process taking place with reactants and products present under nonstandard conditions (pressures other than 1 bar; concentrations other than 1 M) is related to the standard free energy change according to this equation:

Non-ohmic Devices

1.4K
In most substances, the current flow is proportional to the voltage applied to it. A simple relationship between the values of current, voltage, and resistance is known as Ohm's law. Nonohmic devices do not exhibit a linear relationship between voltage and current. One such device is the semiconducting circuit element known as a diode. A diode is a circuit device that allows current flow in only one direction.
Consider a simple circuit consisting of a battery, a diode, and a resistor. A...

Area of Science:

  • Quantum Information Science
  • Cryptography
  • Quantum Computing Security

Background:

  • Quantum cryptography offers unparalleled security, but its practical implementation faces challenges with untrusted devices.
  • Device-independent quantum key distribution (DIQKD) aims to guarantee security without trusting the internal workings of quantum devices.
  • The foundational challenge of DIQKD was posed in the early 1990s.

Purpose of the Study:

  • To rigorously prove the device-independent security of a quantum key distribution protocol.
  • To address the long-standing challenge of achieving secure quantum key distribution with untrusted quantum devices.
  • To demonstrate the robustness of quantum cryptography against general attacks.

Main Methods:

  • Proving the security of a variant of Ekert's entanglement-based quantum key distribution protocol.
  • Analyzing security against the most general (coherent) quantum attacks.
  • Utilizing a new quantitative understanding of quantum correlation monogamy in multiparty settings.

Main Results:

  • The study rigorously proves the device-independent security of the specified quantum key distribution protocol.
  • The protocol demonstrates robustness, achieving a linear key rate and tolerating constant noise.
  • Security is guaranteed even if devices possess quantum memory or share correlations with an eavesdropper.

Conclusions:

  • Device-independent quantum key distribution is achievable, even when quantum devices are untrusted.
  • The presented protocol offers a robust solution for secure communication, relying only on the fundamental laws of quantum mechanics.
  • This work advances the practical realization of highly secure quantum communication systems.
