Boson quantum error correction is an important means to realize quantum error correction information processing. In this paper, we consider the connection of a single-mode Gottesman-Kitaev-Preskill (GKP) code with a two-dimensional (2D) surface (surface-
This breakthrough marks a significant advancement in quantum materials research. The researchers believe that the vortex-like behavior of electrons in momentum space could open the door to new quantum technologies, particularly in orbitronics. Unlike traditional electronics, which rely on an electron’s...
The Hall effect refers to the phenomenon where a voltage is generated perpendicular to the direction of both the current and the magnetic field when a current passes through a material placed in a magnetic field. This effect was discovered by American scientist Edwin Hall in 1879 and has been ...
Quantum interference (QI) is a characteristic quantum effect found in nanoscale charge transport and has been predicted to enhance transistor performance (Fig. 1)6,7,8,9,10,11,12,13. However, it is difficult to create two nanoscale quantum-coherent channels in standard conductors, because ...
Stores information in qubits as 0, 1 or a superposition of 0 and 1. Processes data with quantum logic at parallel instances, relying on interference. Quantum processors do not perform mathematical equations the same way classical computers do. Unlike classical computers that must compute every step...
One benchmark of quantum information processor: To implement Shor's algorithm for 2048-bit RSA[3][4], the smallest number of qubits required to break 2048-bit RSA encryption using Shor's algorithm is: ~4000 logical qubits. By the way, each of these logical qubits is built up by 100~100...
Quantum tunneling is a quantum mechanical effect in which particles have a finite probability of crossing an energy barrier, such as the energy needed to break a bond with another particle, even when that quantum particle’s energy is less than the energy barrier. Because matter is both particle...
Even the most powerful supercomputers on earth would require thousands of years to mathematically break modern encryption algorithms like the Advanced Encryption Standard (AES) or RSA. According to Shor’s Algorithm, factoring a large number on a classical computer would require so much computing power...
one, to store information, quantum computers use quantum bits (or qubits), which can hold any linear combination of zero and one simultaneously (Steane,1998). Qubits leverage the advantage of the properties of quantum mechanics and in particular the effect of superposition (visualization see Fig....

Imagine that level of security with regards to sensitive medical information: electronic health records, genetic and genomic data, or any other private information that the health system generates about our bodies...
