地球是人類(lèi)共同的家園，但是隨著社會(huì)的發(fā)展，人類(lèi)對(duì)地球資源的過(guò)度開(kāi)發(fā)，災(zāi)難性的后果將接踵而至。本文主要介紹了一種新型的汽車(chē)動(dòng)力系統(tǒng)，該系統(tǒng)可以減少燃料的消耗，可以保護(hù)地球的資源。研究人員看好它的發(fā)展前景。

In order to make a car run， its engine burns gasoline and converts the energy from the heat of the burning gasoline into mechanical work. In the process， however， energy is wasted. A typical car only turns around 25 percent of the energy in gasoline into useful energy to make it run.

In order to solve this problem， Andrew Jordan， a professor of physics at the University of Rochester， New York， was recently awarded a three?year， $1 million grant fund from the Templeton Foundation to research quantum（量子） measurement engines—engines that use the principles of quantum mechanics to run with 100 percent efficiency. The research， to be carried out with co?principal investigators in France and at Washington University St. Louis， could answer important questions about the laws of thermodynamics（熱力學(xué)） in quantum systems and contribute to technologies such as more efficient engines and quantum computers.

The team will also investigate another major area of research： how it might be possible to get work out of a system using entanglement（糾纏） as a fuel. In entanglement—one of the basic theories behind quantum physics—the properties of one particle are interlinked with properties of another， even when the particles are separated by a large distance. Using entanglement as a fuel has the possibly revolutionary feature of creating a non?local engine; half of an engine could be in New York， while the other half could be in Cal?ifornia. The two halves can share the same energy resource to fuel both halves at the same time.

When asked about the investment prospects， Jordan said， “We will show that the engine can， in principle， be perfectly efficient. That is， there would be an ideal transfer of energy from the measurement equipment to the quantum system. The University of Rochester has an existing strength in quantum physics， and indeed was the birthplace of the field of quantum optics. We have a good collection of quality researchers in place， a historical legacy of quantum physics， and ongoing university support of quantum physics.”
