- Schrödingers Cat and the Qbit - Physics Forums
If, on the other hand, the cat is truly in a superposition of “alive” and “dead”, then we have a quantum bit of information (qubit or Qbit) Let explain the difference between a Cbit and a Qbit and let you decide
- How Does a Qubit Exist as Both 1 and 0 Simultaneously?
I think 10 more IQ points would help me understand quantum physics at the level I'd like That said, I'd like to know more about Qbits I've watched several videos about them, and they say that they can be 1 and 0 at the same time Is that just an analogy to the polarization of the old
- Finding E_J Value of a Qubit: Step-by-Step Guide
Hi everyone, I’ve performed microwave measurements on a 3D transmon and want to find the E_J value of the qubit I’ve tried searching through many papers, particularly Koch et al, about how to do this, but I am stumped Could someone please help me out? Thanks in advance
- Qubit error rate of QKD BB84 protocol • Physics Forums
Hello everyone, I don't know how to measure the QBER of BB84 protocol in a realistic experiment In the most paper show the data which is only the number but do not show the unit of data, what is the unit of these data?
- Calculating qubit purity entanglement in a quantum computer
I had written a simulator for a quantum computer and wanted to be able to calculate the values of the "purity of reduced states" "Purity of reduced states" is a quantity that IBM provides on their simulator for each qubit They used to call it "entanglement", and I believe that the two terms
- Quantum computer storage capacity - Physics Forums
I have a question regarding the storage capacity of quantum computers I read that 32 qubits (4 "quantum bytes" if you will - not sure if that's an actual

- Understanding Two-Qubit States: The Bell States - Physics Forums
An example of a two-qubit state is one of the Bell states, for example: lB> = 1 √2 (l00> + l11>) In my book it is stated that the Bell states form an orthonormal basis for the set of two qubit states But what exactly is the general form of a two-qubit state? Is it any vector of the form: lq>
