Molecular magnets have been proposed as a promising candidate for spin-based qubits. As a test bed toward scalable qubits, we explore the isosceles antiferromagnetic spin triangle {Cu3-X} (X=As, Sb) impregnated in free standing nanoporous silicon. By using 240 GHz microwave pulses Rabi oscillations were observed and a spin memory time was measured to be T2=1066 ns at 1.5 K. This demonstrates that this hybrid material provides a promising scheme for implementing spin-based quantum gates. Comparing samples with different symmetries and environments we give evidence that spin chirality is the main decoherence source of spin triangle molecules unlike other molecular magnets.
