The radiation detector makes reading the state of the qubit simpler than before.

Dissipation is a phenomenon that destroys quantum entanglement, a necessary resource in quantum algorithms. However, today we discuss how engineered dissipation can in fact aid a quantum processor by steering it into a desired entangled state → https://goo.gle/3UcpX1R

The radiation detector makes reading the state of the qubit simpler than before.

The quantum threshold theorem allows for the possibility of building a quantum computer despite the presence of errors. However, the threshold theorem requires weak noise. There are several error models that are not covered by the threshold theorem. The following table from Daniel Gottesman's book on quantum error correction (https://lnkd.in/gRDcSHpw) provides a nice summary of assumptions/noise models and their impact on the threshold theorem.

Let's see another example of the quantum order-finding subroutine of Shor's factoring algorithm. We can see how a quantum computer can reveal that the order of 7 mod 15 is 4.

Thinking about solving linear systems problems in quantum computers? As you know, we have the best-known asymptotic scaling quantum algorithm for this problem. Now, we show that it is also the best known for practical problems, as you can check in my presentation in QAISG.

Something exciting has been brewing. Though not for the first time, researchers are claiming to have a room temperature, ambient pressure #superconductor. #LK-99 (approx. Pb9Cu(PO4)6O) is the wonder material. The original report came from Korean researchers and can be found at https://lnkd.in/dNueqQ2G Since then there has been a number of reports from rather ivy league research lab scientist potentially trying to explain the observation using simulations. https://lnkd.in/dJxmK8gd https://lnkd.in/d6Gmz-ks https://lnkd.in/da9KG_A2 All of the simulation studies more or less back the original author's claim that Cu atoms substituting the Pb in the crystal introduces strain which results in rather flat energy bands close to the fermi level. There has also been a claim of replication. In any case, the synthesis process is not too complicated and clouds will be cleared before the end of August. If true this will be a paradigm shift in technology. #LK99 Follow https://lnkd.in/dFczFAg3 for much deeper analysis.

Why Quantum Computer can calculate complex calculation faster than classical computer ? What is the concept of Quantum Entanglement ? Why we use Quantum Fourier Transform in Shor's Algorithm? Prime Factorisation of large number using Shor's Quantum Algorithm ?

A faster model based on a novel AF is applied for time-varying generalized Sylvester equation (TVGSE) solving is official online. https://lnkd.in/dWhzkE2s

This recent paper describes an efficient quantum factoring algorithm. Given the with O(n^3/2) gates for sqrt(n)+4 repetitions it seems that factorizing a 2048 bits would only require 500 seconds on a supraconducting quantum computer with gates operating between 1 and 20 nanoseconds 2048^3/2=92681 sqrt(2048)+4=49 92981*49=4541413 gates times duration of gate operation
