¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

¹³C NMR: Distortionless Enhancement by Polarization Transfer (DEPT)

When proton-coupled carbon-13 spectra are simplified by a broadband proton decoupling technique, structural information about the coupled protons is lost. Distortionless enhancement by polarization transfer (DEPT) is a technique that provides information on the number of hydrogens attached to each carbon in a molecule. While the DEPT experiment utilizes complex pulse sequences, the pulse delay and flip angle are specifically manipulated. The resulting signals have different phases depending on...

Double Resonance Techniques: Overview

Double Resonance Techniques: Overview

Double resonance techniques in Nuclear Magnetic Resonance (NMR) spectroscopy involve the simultaneous application of two different frequencies or radiofrequency pulses to manipulate and observe two distinct nuclear spins. One important application of double resonance is spin decoupling, which selectively suppresses coupling with one type of nucleus while observing the NMR signal from another nucleus, simplifying the spectrum and enhancing resolution.
Spin decoupling is usually achieved by...

Area of Science:

Cryptography and Network Security
High-Performance Computing
Quantum Computing Security

Background:

Quantum computers pose a significant threat to existing public key infrastructure (PKI) cryptographic algorithms.
High-performance computing (HPC), data center communications, and governmental systems are vulnerable to quantum attacks.
Post-quantum cryptography (PQC) is being developed to counter these threats, but involves processing overhead.

Purpose of the Study:

To provide an experimental performance comparison of NIST-selected PQC algorithms.
To evaluate PQC implementation on data processing units (DPUs) for practical deployment.
To assess the suitability of PQC for high-capacity data center environments.

Main Methods:

Implemented and tested four NIST-selected PQC algorithms on a data processing unit (DPU).
Conducted experiments at line-rate speeds to simulate real-world network conditions.
Measured performance metrics relevant to data packet processing and throughput.

Main Results:

Demonstrated PQC operation at nearly 100 Gbit/s on DPUs.
Quantified the performance overhead of PQC compared to classical cryptography.
Validated the feasibility of high-speed PQC data processing.

Conclusions:

PQC algorithms can achieve high throughput, suitable for demanding data center environments.
DPU implementation of PQC is viable for transitioning to quantum-resistant security.
This research supports the adoption of quantum-safe cryptographic schemes.
