Quantum Numbers02:43

Quantum Numbers

52.9K
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.

Long-term Potentiation01:35

Long-term Potentiation

59.0K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

Distribution Reliability and Automation

547
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...

Leaky Scanning02:28

Leaky Scanning

5.8K
During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA.  Marilyn Kozak discovered that the sequence RCCAUGG (where R...

The Quantum-Mechanical Model of an Atom

60.3K
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 Maximum Power Transfer Theorem01:20

The Maximum Power Transfer Theorem

1.3K
Consider a linear AC Thevenin equivalent circuit connected to a load impedance.
The load connected draws the current, and the circuit delivers the power to the load. The alternating current flowing through the load is determined using the rectangular form of voltages, currents, network impedance, and load impedance. The average power delivered to the load is obtained from the product of the square of current and load resistance.

Area of Science:

  • Quantum Information Science
  • Cybersecurity
  • Applied Physics

Background:

  • Quantum key distribution (QKD) promises information-theoretic security, but practical implementations face vulnerabilities.
  • Side-channel attacks exploit discrepancies between theoretical models and physical QKD device behavior.
  • Demonstrating security in both theoretical and physical domains is crucial for QKD adoption.

Purpose of the Study:

  • To develop and evaluate a QKD system resilient to various hacking attacks.
  • To validate the system's security against both theoretical and practical implementation flaws.
  • To assess the QKD system's performance and security in a live metropolitan network.

Main Methods:

  • Designed a QKD system incorporating security features against Trojan horse, detector blinding, phase randomization, and photon number splitting attacks.
  • Deployed the QKD system in a 45 km metropolitan telecom network link.
  • Monitored system operation and secure key distribution over a 2.5-month period.
  • Analyzed security against coherent attacks, a broader class than typically considered.

Main Results:

  • The QKD system operated continuously for 2.5 months, distributing 1.33 Tbits of secure key data.
  • A stable secure key rate exceeding 200 kbit/s was maintained.
  • The system demonstrated resilience against multiple hacking attack vectors.
  • Security was validated against advanced coherent attacks.

Conclusions:

  • The developed QKD system offers enhanced resilience against practical implementation vulnerabilities and hacking attempts.
  • Real-world deployment confirms the system's capability for continuous, high-rate secure key distribution.
  • The findings support the practical viability of information-theoretically secure communication networks.
