论文摘要
在许多领域，从物理学的基本问题到独立的密码学都重要。我们提出了一项协议，该协议可以将任何类型的任何类型的非本地非定位框转换为任何其他极端两方的非局部性信号盒 - 两件输入非定位的无信号盒完美地完美。我们的结果是准确的，即使无法提前确定所需框的数量，它们的预期数量也是有限的。我们的协议是自适应的，并首次证明了当事方在不同因果命令中使用无信号的框的有用性。
Understanding the structure of nonlocal correlations is important in many fields ranging from fundamental questions of physics to device-independent cryptography. We present a protocol that can convert extremal two-party--two-input nonlocal no-signaling boxes of any type into any other extremal two-party--two-input nonlocal no-signaling box perfectly. Our results are exact, and even though the number of required boxes cannot be determined in advance, their expected number is finite. Our protocol is adaptive and demonstrates for the first time the usefulness of using no-signaling boxes in different causal orders by the parties.
