Five-Spin Supramolecule for Simulating Quantum Decoherence of Bell States

We report a supramolecule that contains five spins of two different types and with, crucially, two different and predictable interaction energies between the spins. The supramolecule is characterized, and the interaction energies are demonstrated by electron paramagnetic resonance (EPR) spectroscopy. Based on the measured parameters, we propose experiments that would allow this designed supramolecule to be used to simulate quantum decoherence in maximally entangled Bell states that could be used in quantum teleportation.

Automated summary

This study presents a supramolecule with two different types of spins and interaction energies. The interaction energies are confirmed using electron paramagnetic resonance (EPR) spectroscopy. Based on the measured parameters, the supramolecule is suggested for simulating quantum decoherence in maximally entangled Bell states that can be used for quantum teleportation.
