We present an asymmetric controlled bidirectional remote preparation scheme under the control of Charlie. where Alice transmits an arbitrary single-qubit equatorial state to Bob and Bob transmits an arbitrary three-qubit equatorial state to Alice. First. the quantum channel is constructed by using Hadamard ( ${H}$ ) and CNOT operations. https://www.markbroyard.com/best-save-happy-way-ashy-bines-whey-protein-powder-choc-caramel-500g-online-sale-big-deal/
