Summary
We introduce Quantum-assisted Quick UDP Internet Connections (QQUIC), a secure communication protocol using quantum key distribution for enhanced security and potentially reduced network latency compared to traditional methods.
Area of Science:
- Quantum communication

- The QUIC transport protocol is widely used but relies on classical security assumptions.
Purpose of the Study:
- To propose a novel transport protocol, QQUIC, integrating QKD into the key exchange process.
- To enhance communication security beyond classical cryptography.
- To investigate potential latency improvements over standard QUIC.
Main Methods:
- Modification of the QUIC transport protocol.
- Integration of quantum key distribution for secure key generation.
- Utilizing dedicated quantum connections for key exchange.
Main Results:
- QQUIC achieves security independent of computational assumptions, leveraging QKD's inherent properties.
- The protocol demonstrates potential for reduced network latency in certain scenarios.
- Dedicated quantum channels facilitate efficient key generation.
Conclusions:
- QQUIC offers a robust, quantum-secure alternative for internet transport protocols.
- The integration of QKD can surprisingly lead to performance benefits, including lower latency.
- This approach paves the way for next-generation secure and efficient network communications.

Carrier-mediated transport is a pivotal process in drug absorption, particularly for lipid-insoluble drugs, and encompasses facilitated diffusion and active transport. Facilitated diffusion allows drugs to move along their concentration gradient without energy expenditure, while active transport utilizes ATP to drive drug movement against this gradient.
Active transport involves two types of membrane-spanning transporters: uptake and efflux. Uptake transporters are expressed in the small...

16.2K
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.

The chemical and physical properties of plasma membranes cause them to be selectively permeable. Since plasma membranes have both hydrophobic and hydrophilic regions, substances need to be able to transverse both regions. The hydrophobic area of membranes repels substances such as charged ions. Therefore, such substances need special membrane proteins to cross a membrane successfully. In facilitated transport, also known as facilitated diffusion, molecules and ions travel across a...

1.2K
The Reynolds transport theorem provides a framework to relate the time rate of change of an extensive property within a system to that in a control volume, which is crucial for analyzing fluid dynamics. Extensive properties, such as mass, velocity, acceleration, temperature, and momentum, can be expressed in terms of the mass of a fluid portion. These properties are called extensive because they depend on the system's size, while intensive properties are their corresponding values per unit...

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.

The generation of electrical current in semiconductors is fundamentally driven by two mechanisms: drift and diffusion. These processes are essential for the functionality and performance of semiconductor-based devices.
Drift Current:
The drift of charge carriers is started by an external electric field (E). Charged particles, such as electrons and holes, experience an acceleration between collisions with lattice atoms. For electrons, this results in a drift velocity (vd) given by:
