    "abstract": "A scheme is proposed by which two parties, Alice and Bob, can securely\nexchange real numbers. The scheme requires Alice and Bob to share entanglement\nand both to perform Bell-state measurements. With a qubit system two real\nnumbers can each be sent by Alice and Bob, resulting in four real numbers\nshared by them. The number of real numbers that can be shared increases if\nhigher-dimensional systems are utilized. The number of significant figures of\neach shared real number depends upon the number of Bell-state measurements that\nAlice and Bob perform. The security of the scheme against individual\neavesdropping attacks is analyzed and the effects of channel losses and errors\ndiscussed.",
