Quantum Computing with Zero Spin Atoms?

Click For Summary
Building a qubit from an atom with a nuclear spin of zero, such as 16O, 12C, or 32S, raises questions about the reliance on electron spin for qubit functionality. The discussion suggests that electron spin could be a viable alternative for encoding qubits in these cases. The feasibility of using zero spin atoms for quantum computing applications remains uncertain and requires further exploration. Existing literature, including resources like Wikipedia, provides insights into various degrees of freedom employed in qubit encoding. Overall, the potential for zero spin atoms in quantum computing is a topic of ongoing inquiry.

Hello,

Is it possible to build a qubit from an atom with a nuclear spin of zero (ie. 16O, 12C, 32S)? Would it depend on electron spin instead?

Thanks!

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
