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.poolsproductscanadas.shop/product-category/pro-series-filter-parts/
