Story summary

ConQuER, controllable quantum-generation framework by Northeastern University and Cisco Research, enables precise control over output distributions.
It embeds lightweight controller circuits into pre-trained instantaneous polynomial (IQP) circuits, minimizing retraining.
Experiments show 18% reduction in output bias and over 40% improvement in pattern balance.
Scalability remains strong as controller parameters grow linearly, IQP parameters grow polynomially, and 16–25 qubits are supported.
